Typically used for elements up to 60mm, due to the preservation of suitable mechanical properties. The relevant parameters only appear after thermal treatment. The 30HGSA grade from the 30HGS steel differs withmore restrictive S-sulfur and P-phosphorus approvals in the chemical composition. This improves the properties and quality of the product.
30crmnsia Medium Carbon Material High Strength Steel 30CrMnSiA is medium carbon, high strength steel , poor welding performance. 30CrMnSiA after quenching and tempering has a high strength and sufficient toughness, hardenability is also good. After quenching and tempering the material to do the grinding wheel shaft, gear, sprocket can be. 30CrMnSiA has good processability, processing deformation is small, anti-fatigue performance is quite good.

42CrMo4 steel and 42CrMo steel difference WixSteelThe GB/T 3077 of P and S content is classified into three grades. The standard value of EN10083 limits the maximum content. The P and S contents of medium and high quality steel in GB/T 3077 standard are similar to those in EN10083 standard. The content range of Si and Mo in GB/T 3077 standard is narrower than EN10083 standard. If only chemical
GB 20CrMnTi GB/T 3077 In addition to carbon, steel also contains a small amount of manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and hydrogen (H). These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements.

There have been some changes in this nationals standard over its previous edition in the following technical aspects:- Change the name of the standard to Alloy Structure Steel; - After consultation between the two sides of supply and demand, the bar stock of which the
SLM-manufactured 30CrMnSiA alloy:Mechanical properties Nov 01, 2018 · 1. Introduction. 30CrMnSiA alloy is a type of medium carbon steel, which has a high tensile strength and good weldability and been broadly applied in pressure vessel and aerospace industrial fields , , .In recent decades, manufacturing methods of 30CrMnSiA parts contains casting, forging and extrusion and so on , , .Those traditional processes generally need external moulds or
GB-T 3077-2006 15CrMo is a steel pearlite colony Heat-resistant steel, GB-T 3077-2006 15CrMo has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
