303 STAINLESS STEEL PIPE

Stainless steel pipe is a hollow, long, round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils.

303 grade stainless steel is also known as 1.4305 type stainless steel. 303 grade is the easiest to process among all austenitic stainless steels. The machinability of 303 grade is due to the presence of sulfur in the steel element. Sulfur can improve machining, but it also reduces corrosion resistance and toughness. The corrosion resistance of 303 is lower than that of 304, but the toughness is still as excellent as other austenitic grades.


PRODUCT USES

Common applications for stainless steel pipes include food processing, textile business, breweries, water treatment plants, oil and gas processing, fertilizers and pesticides, chemical applications, construction, pharmaceuticals, automotive parts, etc.
