EN10250 4 1 What is 4028 in China

It is equivalent to X30Cr13, C content to, Si maximum, Mn maximum, P maximum, S maximum, Cr content to, and the above element content is a percentage.

Summary. Hello dear, glad to answer for you! The corresponding national standard is stainless steel cast steel. Cast steel refers to steel that is used exclusively for the manufacture of steel castings. When the strength requirements of the casting are high and the cast iron cannot meet the requirements, cast steel should be used.

Corresponding to the national standard. Hello dear, glad to answer for you! The corresponding national standard with lead is stainless steel and cast steel. Cast steel refers to steel that is used exclusively for the manufacture of steel castings.

When the strength requirements of the castings are high and the use of cast iron cannot meet the requirements, it is necessary to use the disadvantage of casting steel.

Extended information: The national standard is a national standard code that includes a language coding system, which is issued by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (or International Electrotechnical Association, IEC) member body representing the People's Republic of China: Haozhenshi National Standard Friendship Car Management Committee.

Standards published in 1994 and earlier use 2 digits to represent the year. Since 1995, the standard has been issued, and the year after the standard number has been changed to 4 digits.

It belongs to the European standard martensitic stainless steel, and the implementation standard: DIN EN 10250-4-2018

The steel has good mechanical processing performance, after heat treatment (quenching and tempering), it has excellent corrosion resistance, high polishing performance, high strength and wear resistance, and is suitable for manufacturing plastic molds that bear high load, high wear resistance and under the action of corrosive medium. After quenching and tempering treatment, the material with hardness below HRC30 has good processability and is easy to achieve better surface quality. When the hardness is greater than HRC30, the surface quality of the parts processed is better, but the tool is easy to wear.

Therefore, after the material enters the factory, the hardness of the quenching and tempering treatment is first carried out to reach HRC25 30, and then the cutting is carried out.

The chemical composition is shown below:

From the perspective of chemical composition, it is equivalent to the domestic grade: 3cr13

It is the digital code of the German standard, and the corresponding grade is: X30CR13, and the implementation standard EN10250-4
