Very good. 1905 steel is very good.

1. Hardness, elasticity, antimagnetic force, anti-mechanical properties and wear resistance of steel.

2. Strength, toughness, heat resistance, anti-corrosion, acid resistance, magnetic permeability, etc. of steel. Steel is a general term for alloys with a carbon content ranging from 0.02% to 2.11% by mass. The chemical composition of steel can vary greatly. Steel containing only carbon elements is called carbon steel or ordinary steel. In actual production, steel often contains different alloying elements according to different uses, such as: manganese, nickel, vanadium, etc. wait. The application and research of steel has a long history, and the preparation of steel is a high-cost and low-efficiency task.
