Stpy41 steel pipe refers to seamless steel pipe, which is a brand under Japanese standards. This steel pipe has relatively high strength, good corrosion resistance, low temperature resistance and good toughness. Stpy41 steel pipe is used to transport low-pressure fluids. This type of steel is generally smelted in a converter or an open hearth. Its main raw materials are molten iron and scrap steel. The sulfur and phosphorus content in the steel is higher than that of high-quality carbon structural steel. Generally, sulfur is ≤0.050% and phosphorus is ≤0.045%. The manufacturing process of Stpy41 steel pipe is relatively complex and requires multiple heat treatments and cold processing to ensure that its performance indicators meet the requirements.
Stpy41 steel pipe has a wide range of uses and can be used to make automobile parts, machine tools, bearing seat covers, gear devices, valves, pipe fittings, etc.
