What does ZG30CR18MN12SI2N mean Hello dear, 1, ZG30 and No. 30 steel have almost the same chemical composition. 2. ZG30 specifically refers to the cast steel with carbon content around it, No. 30 steel refers to steel with carbon content, and Datong mostly refers to the forging wheel or hot and cold No. 30 steel. Hope it helps.

If my answer is helpful to you, please give a thumbs up (comment in the bottom left corner), look forward to your likes, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Kiss! Hello, happy to answer your <>

What does Zg30Cr18Mn12Si2N mean as follows: This is a cast steel grade, which means that the cast steel material ZG30 obtained after nitriding treatment with carbon content, chromium, manganese and silicon? ZG30 specifically refers to the cast steel with a carbon content of about the left, and No. 30 steel refers to the steel with carbon content, and in most cases refers to the No. 30 steel that is made or hot, cold.

Medium carbon cast steel, ZG35 is the old standard before, equivalent to the current ZG270--500. Its carbon content is between, the new standard wheel is not marked by carbon content, but by mechanical properties as the grade, 270 is the yield strength, 500 is the tensile strength, and the carbon content is not indicated. The mechanical properties of ZG35 are slightly lower than those of structural steel or high-quality steel with the same carbon content, because it has a wider requirement for P and S content.

Hope mine can help you <>

High manganese steel. High manganese steel is a type of anti-wear steel designed for use in heavy industries such as anti-disturbance quarrying, mining, excavation, coal industry, foundry and steel industry.

After being treated with anti-wear technology, the surface of the material can reach 500-550 cloth hardness, continue to maintain internal flexibility, minimize surface friction, can be welded with high manganese steel or similar materials, can be cut by acetylene oxygen torch, non-magnetic, etc.

ZGMN13-4 is a high-manganese steel with casting process, which is characterized by high wear resistance and low impact resistance; It is commonly used to make bucket teeth of excavators, crushing walls of crushers, lining plates of ball mills and other abrasive parts, with carbon content and manganese content; Similar products are ZGMN13-1, ZGMN13-2, ZGMN13-3, the following 1, indicating the level, generally different carbon content, such as ZGMN13-1 carbon content, ZGMN13-2, ZGMN13-3.

ZGMN13-4 is a grade of high manganese steel.

The content is C:,Mn:,Si:,Cr:,S,P The difference between ZGMN13-4 and ZGMN13-1, ZGMN13-2, ZGMN13-3 and ZGMN13-5 is mainly that contains CR elements.

ZGMN13-5 contains MO

ZGMN13-1, ZGMN13-2, and ZGMN13-3 are all C, SI, MN, S, P, and the difference is that the content is different.

The carbon content range of ZGMN13-3 fluctuates smallly, the content of S and P elements is low, and the material strength is high. There is no difference between MN and Si content.

ZG03CR19Ni11MO2 is actually compared from the American standard material CF3M, which is also the casting form of 316L stainless steel.

Anti-oxidation steel, steel with good oxidation resistance at high temperature and a certain strength.

Commonly used oxidation resistant steels 3Cr18Mn12Si2N, 2Cr20Mn9Ni2Si2N, 3Cr18Ni25Si2, etc., they will form Cr2O3, SiO2, Al2O3 oxide films, improve oxidation resistance, sulfur resistance and carburizing resistance, and also have good shear, stamping and welding properties. Adding rare earth elements such as LA and CE to CR steel can not only reduce the volatilization of CR2O3 but also form a more stable (Cr, La)2O3; It can also promote the diffusion of chromium, which is conducive to the formation of Cr2O3 and further improves the oxidation resistance. Generally, solution treatment is used to obtain a homogeneous austenite structure.

Can be used for parts with operating temperatures up to 1000 °C.
