Abstract

The invention provides stainless steel alloy material. The stainless steel alloy material comprises, by weight, 0.05-0.10 part of C, 10-20 parts of Cr, 3-5 parts of Mo, 5-7 parts of Ni, 0.1-0.5 part of Cu, 0.2-0.8 part of Si, 0.3-0.6 part of Mn, 0.1-0.5 part of B, 0.1-0.8 part of Ti, 0.1-0.3 part of Al, 0.01-0.05 part of N, 0.01-0.05 part of S, and 80-100 parts of Fe. The stainless steel alloy material has the advantages of corrosion resistance, wear resistance, less easiness in passivation.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a stainless steel alloy material. Background technique [0002] Stainless Steel (Stainless Steel) refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requiremen...
