What is the difference between 06cr13 stainless steel plate and 0cr13 stainless steel plate

0CR13, or American Standard 410S, is the lowest carbon content in CR13 martensitic stainless steel. Due to the ferrite structure of the matrix in the annealed state, it is also classified as ferritic stainless steel in a few standards.

<> corrosion resistance is similar to and better than 1Cr13(410), and it has corrosion resistance at low concentrations of mild organic and inorganic acids, alkalis and some chemicals.

It has good antioxidant properties and can be used in the 705 environment for a long time.

It has good plasticity and is easy to form by rotating, bending and rolling.

It can be welded by common fusion and resistance techniques.

The main product form of 410 is plate, which is used to manufacture structural parts such as automobile mufflers and exhaust system components, and is also widely used in containers, heat exchangers, underground pipelines, etc.

06CR13 is the new national standard.

0cr13 is the old national standard designation.

Actually a kind of stainless steel、Same。

The difference between the carbon content of 06Cr13 stainless steel plate and 0Cr13 stainless steel plate, the company can be fixed and flattened in stock of TISCO.

0Cr13 is the one with the lowest CR content among martensitic stainless steels. It is stainless and corrosion resistant better than 1Cr13, 2Cr13, 3Cr13, 4Cr13 martensitic stainless steels with high carbon content. It has good plasticity, toughness and cold formability, and is superior to other martensitic stainless steels with higher CR content.

When the C content of 0Cr13 steel is very low, its plasticity, especially toughness, and cold formability will be significantly improved. 0Cr13 steel is mainly used in the manufacture of water vapor resistance, ammonium bicarbonate mother liquor, hot sulfur petroleum corrosion parts and equipment linings, etc. The corresponding U.S. grade of this steel grade is 405, and the specific gravity is, 0Cr13 is the lowest CR content among martensitic stainless steels.

<>30cr13 is a martensitic stainless steel. 30Cr13 usually refers to martensitic stainless steel with relatively high carbon content, which belongs to food-grade steel. Martensitic stainless steel is a stainless steel whose mechanical properties can be adjusted through heat treatment, and is mainly used for steam turbine blades, tableware, and surgical instruments.

According to the difference in chemical composition, martensitic stainless steel can be divided into two categories: martensitic chromium steel and martensitic chromium-nickel steel.

Introduction of 3Cr13 steel.

China 30Cr13 (3Cr13 steel) is a martensitic stainless steel, which has good machinability. After heat treatment (quenching and tempering), it has excellent corrosion resistance and high polishing strength and wear resistance. After quenching and tempering, when the hardness is below HRC30, the 3Cr13 material has good machinability and is easy to achieve good surface quality, when the hardness is greater than HRC30, the surface is ***, but the tool is easy to wear.

Compared with 1Cr13 (12Cr13) and 2Cr13 steels, 3Cr13 stainless steel has higher strength, hardness, and higher hardenability. It has certain corrosion resistance in dilute nitric acid and weak organic acids at room temperature, but it is not as good as 1Cr13 and 2Cr13.
