Hard Stainless Steels

Of course stainless steels are well known for their resistance to corrosion but these steel can also be considerably strong depending on how they are produced.

Hard stainless steels.

200 series stainless steel. Lightly drawn 660 max. Stainless steel hardness is one of the most important characteristics when choosing the material for a specific application. Austenitic steels form the largest portion of the global stainless steel market and are often used in food processing equipment kitchen utensils and piping.

3 different types of stainless steel include the elements carbon from 0 03 to greater than 1 00 nitrogen aluminium silicon sulfur titanium nickel copper selenium niobium. Tempering and hardening is possible due to added carbon making this family a leading choice for knives scissors razors and medical tools. Available in three grades 440a 440b 440c more common and 440f free machinable. It can also be quickly hardened by machining.

It has good malleability and applied in forming products. Hardening martensitic stainless steels martensitic stainless steels could be described as the most conventional alloy in terms of its hardenability properties. While the least common of the four major stainless steel families martensitic and precipitation hardening steels are popular in applications requiring a precise hardened edge. Hardness max note 2 austenitic stainless steels plate annealed 600 310 40 95 hrb sheet annealed 515 205 40 95 hrb or coil 1 4 to full hard 860 1275 515 965 25 9 wire annealed 605 max.

They typically display a proportional hardenability to carbon c content and are subsequently suited to standard austenitizing quenching and tempering. Contain chrome nickel also belongs to austenitic stainless steel. 2 5mm dia. 3 a composition that prevents the iron from rusting as well as providing heat resistant properties.

300 series stainless steel. 276 is a family of iron based alloys that contain a minimum of approximately 11 chromium. An air hardened semi stainless steel d2 has a relatively high chromium content 12 percent which makes it more stain resistant than other carbon steels. Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel.

Other major alloying elements include manganese silicon and carbon. And over bar cold finished 262 hb condition a plate annealed 515 205 40 92 hrb plate annealed 485 170 40. It has shown excellent wear resistance and edge retention and is tougher than most stainless steels such as ats 34 although less so than other non stainless grades. Also known as razor blade steel.

Ferritic steels contain trace amounts of nickel 12 17 chromium less than 0 1 carbon along with other alloying elements such as molybdenum aluminum or titanium.
