SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1] The name comes from the chemical makeup which is approximately 17% chromium and 4 ...
A2 stainless steel outside the US, in accordance with ISO 3506 for fasteners. [4] 18/8 and 18/10 stainless steel (also written 18-8 and 18-10) in the commercial tableware and fastener industries. SUS304 the Japanese JIS G4303 equivalent grade. 1.4301, the EN 10088 equivalent. [5] 06Cr19Ni10 and ISC S30408, the equivalent in Chinese GB/T 20878 ...
In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
Stainless steel is used in a variety of applications in dentistry. It is common to use stainless steel in many instruments that need to be sterilized, such as needles, [42] endodontic files in root canal therapy, metal posts in root canal-treated teeth, temporary crowns and crowns for deciduous teeth, and arch wires and brackets in orthodontics ...

420HC (420C) is a higher carbon content 420 stainless steel. The HC stands for "high carbon" and it can be brought to a higher hardness than regular 420 and should not be mistaken for it. Buck Knives, Gerber Knives and Leatherman use 420HC extensively. [7] 420A (420J1) and 420B (420J2) are economical, highly corrosion-resistant stainless steel ...
Mild steel ultimately replaced wrought iron for almost all purposes, and wrought iron is no longer commercially produced. With minor exceptions, alloy steels only began to be made in the late 19th century. Stainless steel was developed on the eve of World War I and was not widely used until the 1920s.
