steel can be found in most machine shops, as it is an easy metal to machine when annealed and yet is strong and resilient when heat treated. This material is exceptionally good for components that must resist corrosion relatively well and yet not wear under repeated use. It is a great steel for knife edges, as its hardness yet formability excels when used for kitchen cutlery. There are some other notable applications of 440 steel, listed below: As you'd expect, the large‑diaphragm design makes the SE4400 very good as a vocal microphone, and it should be quite flexible in this role, as long as you don't need to hype up the vocal sound too much. I even managed to make some good violin recordings, in which the top end of the instrument sounded very close to how I heard it in the room. Normally, I'd generally go for a mic with a more rounded‑sounding top end for recording violin, but I was putting this mic through its paces, after all, and the result I got responded very well to some gentle top‑cut EQ. When used with an appropriate threshold seal, and door, the 1212 has an R wof 31dB when used with an acoustic doorset assembly. Karp, Theodore (1983). Dictionary of Music. Northwestern University Press. p.406. ISBN 9780810106598. The SE4400a is clearly designed as a general‑purpose mic, so I wasn't surprised to find that it had no overbearing tonal characteristics. Its presence peak gives it a slightly flattering, larger‑than‑life vibe, but in a pretty subtle way that doesn't make things sound too harsh, and the low end gains useful support from a little added warmth. The general tonality also remained reasonably consistent between patterns — taking the proximity effect out of the equation, of course.

I’ve been very impressed with the level of quality I’ve been getting from the MKE 440, so much so that I’ve switched to using it for all future videos, I mean why wouldn’t you. It captures sounds without losing any tones making it ideal for audio voice recordings and there’s next to no tweaking that needs to be done in post. Sennheiser also states that it’s ideal for musical instrument and ambient recordings too. At least you get your money’s worth when it comes to equipment, as you’d hope given the car’s price. Dynamic SE trim features LED lights, two-zone climate control, a powered tailgate, all-round parking sensors and a 3D-surround camera set-up. steel has impressively high strengths, as can be seen through its ultimate and tensile yield strengths. These measures come from experimental stress tests, where a specimen of 440 steel is pulled apart axially and its strain vs. stress is plotted on a curve. The yield stress is the maximum amount of stress a specimen can experience before plastically (or permanently) deforming, and the ultimate strength is the maximum stress experienced by the specimen before it fractures. These measures are useful in structural applications, where a material must not permanently deform under intense weight, and in high-stress applications where failure must not occur. During welding, grade 440 stainless steels are pre-heated at 250°C, followed by full annealing. Grade 420 filler rods can be used to achieve a high hardness weld. Grade 309 or 310 filler rods will, however, provide soft welds, having high ductility.

For example, the sE4400a is easy to position so its capsule is just peeking over the top of the rim of a snare drum. Speaking of the capsule, it's based on a retuned version of the capsule in the SE2200A (I wish SE Electronics were consistent with capitalization of their product names), which I consider one of the best values in microphones; I use it more often than mics in my closet that cost ten times as much. In direct comparison to the SE2200A (Tape Op #48), the sE4400a in cardioid mode brings out significantly more of the snare drum's punch whether up close, at medium distances, or placed far. I can hear much more resonance of the drum's body. There is perceivably less of the actual snare wires coming through, no matter how I angle the mic, but also less of the undesirable "spit". Hypercardioid and figure-8 modes are useful for rejecting high-hat bleed, but of course, polar-response selection also affects how much room and "floor" (reflection of the snare from the floor -or in my case, a clipboard lying flat on the rug below the snare) the mic captures.

This article presented a brief summary of the properties, strength, and applications of 440 steel.

Sources:The item has lots of wear and tear including scratches, dents, chips, tarnishing and in the case of amps, tears in the tolex covering. The following section discusses the properties of grade 440 bar products covered under ASTM A276. These values may not be similar to that of other forms such as forgings and plates. The 4xx class of stainless steels are alloyed with chromium and are ferritic or martensitic in structure. 440 steel actually refers to four types of steel: 440A, 440B, 440C and 440F steel, which only differ based on the level of carbon in their composition. All types of 440 steel are popular choices, but 440C steel is the most popular of the four, as it has the highest hardness. Below are the chemical compositions of each type:

The item has been heavily used with lots of cosmetic wear and tear. This can include deep scratches, large chips, heavy tarnishing to the hardware and strong discolouration. Hardening — Grade 440 stainless steels are heated at 1010 to 1065°C, then quenched in air or oil. Oil quenching is usually carried out for heavy sections. Following this process, these steels are tempered at temperatures from 150 to 370°C, to achieve a high hardness and improved mechanical properties.

But when switched to omni, the sE4400a excels at bringing out the "air" at 10 kHz and above, without being icy in the 5-7 kHz range. Therefore, for drum overhead work or even as a drum room mic, the mic can help cymbals come to life without making them overly trashy. And as a room or booth mic for adding real depth to vocal recordings, omni is the way to go. By turning the mic, you can "EQ" the room. Whether you're searching for a single microphone to carry out all of your recording tasks, or looking to add to an existing library of models with a microphone you can throw into a bag for a session and pull out for almost any application, the 4400a is definitely more than up to the job.Above a drum kit, on piano, in front of an orchestra, and much more, the sE Electronics sE4400a Matched Pair can do it all!

Grade 440 stainless steels can be easily machined in their annealed state. Machining these grades after hardening is extremely difficult, or impossible in some cases. Whether buyers actually plump for the Range Rover Sport for its extra dynamic edge, or the difference in style compared with the new full-fat Range Rover, this latest Sport redesign isn’t as radical as the one its bigger brother received. Instead, it’s more of a concentrated, focused evolution of the breed, with the brand’s ‘reductionism’ theme being successfully applied to the Sport’s still vast but hunkered-down body. In our opinion, at least. These have to be one of the most versatile mics on the market, as they do it all and do it in effortless, impressive fashion.You can find any number of Chinese‑built microphones at the budget end of the market, but SE are one of the very few companies to own a microphone factory in China — rather than having their mics made for them in one of the huge factories in Shanghai or Bejing that specialise in building mics or capsules for third‑parties. Certainly, this has helped SE to build a strong reputation for value at the affordable end of the market, but they also make more up‑market microphones, many with innovative design features, such as the Titan's titanium diaphragm or the Gemini's dual-tube, transformerless circuitry.
