JIS G3458 alloy steel pipes are usually used in applications that require high strength, corrosion resistance and high temperature resistance, such as petroleum, chemical, energy, machinery and other fields. It can meet specific working pressure and temperature conditions and is one of the important materials in the industrial field.
The alloy steel pipes in the JIS G3458 standard include STPA12, STPA20, STPA22 and other models, each of which has its specific chemical composition and mechanical performance requirements.
