Jul 16, 2008 · What's better, 420 or 440 grade stainless steel? Theoretically, 440, but why? Does it really matter? I collect swords, knives, and so on -- in a couple of my catalogs they really highlight the whole 440 thing. Is that such a big deal? Or is it just for collectors who are, shall we say, more "hardcore" than I am?

Type 420 Stainless Steel is very tough and can be difficult to weld in its annealed or hardened/tempered condition. However, it is easily machined in its annealed state. Because of its excellent properties, you will find Type 420 Stainless Steel in a variety of industries and applications including: Dental and surgical instruments; Pump shafts Page 3 Material Data Sheet 1.4713 06/2017 Material Data Sheet thyssenkrupp Materials (UK) Ltd Stainless Steel 1.4713 Products with thicknesses > 3mm must be preheated up to 600 - 800°C, concerning machinability 1.4713 can be compared to low carbon steel. Stainless Steel AISI 420 / 420c Description These high grade stainless steel balls have a lower chrome content than the 440C versions - which reduces the cost - but otherwise they have similar characteristics: notably a high resistance to corrosion from fresh water, steam, ammonia, petroleum products, blood, perspiration, alcohol and food. Warm-needling (also called thermo-acupuncture) is a combination of acupuncture and moxibustion. Due to the intense heat involved, there have been concerns over the biological safety of the acuneedles used in the treatment. This paper reports two phases of a safety test. For a preliminary test, we ...
