factory direct sell 304 stainless steel square tube
The 304 stainless steel square tube is a form of address for a square tube, that is, a steel pipe with equal length, which is made of strip steel through process treatment. Generally, the strip is dismantled, leveled, curled, and welded to form a circular tube, then rolled into a square tube and then cut into a required length.
304 stainelss steel square tube can be devided into two types: seamless and welded.
Range usage of 304 stainless steel square tube:
304 stainless steel square tube, as a stainless steel heat resistant steel, is used for food equipment, general chemical equipment, and atomic energy industrial equipment.
304 stainless steel is more resistant to rust than 200 series of stainless steel. High temperature resistance is also better, can be up to 1000-1200 degrees. 304 stainless steel square tube has excellent corrosion resistance and better intergranular corrosion resistance.
304 stainless steel has a strong corrosion resistance in material concentration of more than 65% of boiling temperature following nitrate. It also has good corrosion resistance for alkali solution and most organic acids and inorganic acids. It is a high alloy steel corrosion resistance in the air or chemical corrosion and stainless steel is a beautiful surface and good corrosion resistance, which is without plating surface treatment, its inherent surface properties of stainless steel is used in many aspects of steel and often called stainless steel.
Mechanical properties of 304 stainless steel square tube:
1)The ultimate tensile strength of B (MPa) = 520
2)Conditional yield strength (MPa = 205) 0.2
3)5 elongation (%) = 40
4)Section shrinkage (%) = 60 PSI
5)Hardness: = 187HB; 90HRB = 200HV
