Abstract

An iron alloy comprises (wt%): C 0.01-0.22, Si 0.08-1.00, Mn 4.5-12.00, P 0.02-0.2, S 0.025-0.06, Ni 3.50-22.00, Cr 15.00-24.00, Mo 0.05-6.00, and balanced with Fe. It is of explsion-proof and no sparks so as to be used to make containers for dangerous or chemical materials or the other explosion-proofing tools or apparatus.

Description

Technical field [0001] The invention relates to an iron alloy, in particular to an iron alloy material with collision, friction, non-sparking and explosion-proof properties. Background technique [0002] Existing non-sparking metal materials are mainly copper alloy materials. Equipment and tools made of non-sparking copper alloy materials. Due to hardness defects, the service life of equipment and tools is greatly reduced, and the working cost remains high. This has long troubled the industry. development of. [0003] Chinese Patent Application No. 85103868 discloses an iron alloy whose weight percentage components are: carbon 2.00-3.25, manganese 0.40-1.2, silicon 0.40-0.90, chromium 0.70-1.50, boron 0.60-1.2, phosphorus ≤ 0.05, sulfur ≤ 0.05 , The iron balance is 100%, and the less phosphorus and sulfur content, the better. [0004] Chinese Patent Application No. 86102537 discloses a hard wear-resistant iron alloy. Its weight percentage composition is: carbon 2.50-3.00, mangane...
