What material is XM-19 What material is XM-19.
The specific chemical composition of XM-19 is:
c: ≤0.06,
si: ≤1.00,mn: ≤1.00,
p: ≤0.040,
s: ≤0.030,cr: 20.50-23.50,
ni: 11.50-13.50,
mo: 1.50-3.00,
n: 0.12-0.20
XM-19 stainless steel has excellent corrosion resistance, including excellent performance in corrosive media such as chloride, nitric acid, sulfuric acid, etc. It also has resistance to stress corrosion cracking and good wear resistance.
XM-19 has higher tensile strength and yield strength, which is higher than general austenitic stainless steel. Its mechanical properties can be further improved by heat treatment.
XM-19 stainless steel is easy to machine and form, and can be cold and hot worked, such as cold rolling, cold heading, heat treatment, welding, etc. It still retains good plasticity and plasticity at high temperatures.
XM-19 stainless steel is widely used in chemical, marine, aerospace, medical equipment, food processing and other fields. Common applications include marine equipment, valves, drive shafts, bolts, pumps, and valve parts.
XM-19 stainless steel processing technology:
1.Cold working: XM-19 stainless steel is suitable for cold working, such as cold rolling, cold drawing, cold drawing, etc. Cold working can meet specific needs by changing the shape and size of the material without affecting the properties of the material.
2.Hot working: XM-19 can also be hot working, such as hot rolling, forging, heat treatment, etc. Thermal processing is usually carried out at higher temperatures to alter the structure and properties of the material to achieve the desired shape and performance requirements.
3.Welding: XM-19 can be used for conventional welding methods, such as TIG welding, MIG welding, arc welding, etc. Before proceeding with welding, it is advisable to clean and remove oxides from the surface and to select the appropriate welding current and shielding gas.
4.Processing precautions: When processing XM-19 austenitic stainless steel, the following matters need to be noted:
Use high-hardness, sharp tools for better cutting results.
Provides adequate cooling lubrication to reduce cutting heat, reduce case hardening and tool wear.
Avoid long dwell and excessive heat treatment to prevent lattice changes and deterioration of material properties.
