A335 seamless pipe is mainly composed of carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum, and has a variety of performance advantages:

High strength: its tensile strength ≥415Mpa, yield strength ≥205Mpa, elongation after breaking ≥30%, showing excellent mechanical properties.

Good toughness: The content of phosphorus and sulfur is controlled at a low level to ensure the toughness of the steel pipe.

High temperature resistance and oxidation resistance: The addition of chromium and molybdenum improves the high temperature resistance and oxidation resistance of the steel pipe, so that it can still maintain stable performance under high temperature environment.

Corrosion resistance: it has excellent corrosion resistance and can be used in harsh environments for a long time without significant performance degradation.

Excellent processing performance: good welding performance and processing performance, convenient for cutting, bending, welding and other subsequent processing.

 

Application Field Of A335 Alloy Steel Pipe

Because of its excellent performance, this steel pipe has been widely used in many fields:

High pressure boiler: mainly used for high pressure boiler heating surface, economizer, collector, superheater, reheater and other parts, can withstand high temperature and high pressure working environment, to ensure the safe and stable operation of the boiler.

Petrochemical: In the petroleum and chemical industries, it is widely used to transport fluid media, such as oil, natural gas, steam, etc.

Electricity and nuclear power: It provides reliable material guarantee for these industries.
