Hard Stainless Steels

Contain chrome nickel also belongs to austenitic stainless steel.

Hard stainless steels. Tempering and hardening is possible due to added carbon making this family a leading choice for knives scissors razors and medical tools. Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel. They typically display a proportional hardenability to carbon c content and are subsequently suited to standard austenitizing quenching and tempering. Contain chrome nickel manganese belongs to austenitic stainless steel.

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. 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. 276 is a family of iron based alloys that contain a minimum of approximately 11 chromium. Other major alloying elements include manganese silicon and carbon.

It contains high nickel content that is typically between 8 and 10 5 percent by weight and a high amount of chromium at approximately 18 to 20 percent by weight. 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. And over bar cold finished 262 hb condition a plate annealed 515 205 40 92 hrb plate annealed 485 170 40. Also known as razor blade steel.

Stainless steel hardness is one of the most important characteristics when choosing the material for a specific application. It can be hardened to rockwell 58 hardness making it one of the hardest stainless steels. 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. 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.

Austenitic steels form the largest portion of the global stainless steel market and are often used in food processing equipment kitchen utensils and piping.

200 series stainless steel. 2 5mm dia. It can also be quickly hardened by machining. 3 a composition that prevents the iron from rusting as well as providing heat resistant properties.

Available in three grades 440a 440b 440c more common and 440f free machinable.
