There are three fundamental differences between 304 stainless tubing and carbon steel.
First, 304 stainless tubing will undergo work hardening during cold working, for example, they have anisotropy when bent, that is, the transverse and longitudinal properties are different. Due to cold working, 304 stainless tubing has higher strength, which can improve the safety factor to a certain extent.
Second, 304 stainless tubing and carbon steel have different stress/strain curve shapes. The elastic limit of 304 stainless tubing is about 50% of the yield stress. As far as the minimum value specified in the standard is concerned, the yield stress value is lower than that of medium carbon steel.
Third, unlike carbon steel, 304 stainless tubing has no yield point, and the yield stress is usually expressed as an equivalent value with ó0.2.
304 stainless tubing has austenitic stainless steel at room temperature. When the steel contains about 18% Cr, 8%-10% Ni, and about 0.1% C, it has a stable austenite structure. The austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and the high Cr-Ni series steel developed by adding Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements on this basis.
304 stainless tubing from ss tube manufacturer is non-magnetic and has high toughness and plasticity, but its strength is low, and it is impossible to strengthen it through phase transformation. It can only be strengthened by cold working. Such as with S, Ca, Se, Te and other elements added, it has good machinability. In addition to resistance to oxidizing acid medium corrosion, this type of steel can also be resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu.
