What is 20Cr13?

Chinese 2Cr13 steel (20Cr13) is a martensitic stainless steel with magnetic properties, good corrosion resistance and high hardness in the quenched state.

How hard is 420 stainless steel?

As such, after heat treatment, they achieve high levels of hardness, strength and wear resistance. In fact, at 50 HRC, grade 420 stainless steels achieve the highest hardness level of all 12\% chromium stainless steels.

How is martensitic stainless steel made?

They are hardenable by heat treatment (specifically by quenching and stress relieving, or by quenching and tempering (referred to as QT). The alloy composition, and the high cooling rate of quenching enable the formation of martensite. Untempered martensite is low in toughness and therefore brittle.

What is W2 steel?

W2 steel is water hardenable high carbon low alloy steel with a carbon percentage above 1\%. This steel is most commonly used in knives, cutting tools, and large blades due to an excellent combination of high hardness, optimum toughness, and refined grain size.

How is martensite formed?

Martensite is formed in carbon steels by the rapid cooling (quenching) of the austenite form of iron at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe3C). A very rapid quench is essential to create martensite.

What is the difference between 420 and 416 stainless steel?

420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. The higher carbon content employed in 420 gives higher strength and hardness over stainless grades 410 and 416.

What is meant by martensitic?

Martensitic is a descriptive term used to refer to martensite stainless steel. Martensite stainless steel is a type of steel with added carbon and a body-centered tetragonal crystalline structure.

What type of stainless steel is martensitic?

The most common types of martensitic stainless strip grades are 410 Stainless Steel, 420 Stainless Steel, and 440A. These martensitic stainless steels react to heat treatment much like high carbon steel alloys. The maximum quenched hardness depends primarily on the carbon content.

Is W2 a stainless steel?

W2 is the classification for stainless steel hose clamps (combination of AISI430 and zinc plated screw) that can be used in corrosion sensitive environments.

Is martensite good or bad?

So, it can be concluded that martensite has both good and bad effects and an optimum fraction of martensite phase is needed to increase fatigue life.

Is there a 2cr13 steel?

There’s no 2Cr13, but the nearest is X04Cr12, which contains Carbon 0.08\% max and Chromium 11.5 – 13.5\%. These are Ferritic Stainless steels used in parts requiring high ductility and subjected to impact loads. They have good resistance to corrosion in air, in water and in steam.

What is the difference between 2cr13 and X20Cr13?

As per BIS Standard (IS 1570 Part 5 – 1985), steel designation X20Cr13 is an alloy steel containing Carbon 0.16 – 0.25\% and Chromium 12 – 14\%. There’s no 2Cr13, but the nearest is X04Cr12, which contains Carbon 0.08\% max and Chromium 11.5 – 13.5\%.

What is the meaning of 20cr13?

Steel grade designation of 20Cr13 = 2Cr13 stainless steel 20 (or 2) – Average carbon content: 20/10,000 (0.2\%), old designation is 2/1,000 Cr – Chromium symbol 13 – Average content of chromium: 13\%

What materials can be used for X20Cr13?

Stainless Steel, Special Steel, Compressor Blading, Turbine Blading, Superalloy Supplier. X20Cr13 can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. electroslag, forged ring/ block,etc.
