The 304 stainless steel square rod is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel. High temperature resistance is also good, the general use temperature limit is less than 650 °C.
304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion.
For oxidizing acids, it is found in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid below the boiling temperature of ≤ 65%.
It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
304 stainless steel square bar material
As a kind of widely used steel, 304 stainless steel square bar has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon (no magnetic, use temperature -196 ° C ~ 800 ° C).
304 stainless steel square rod use:
Household items (1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, ship parts.

303 stainless steel rod and 304 stainless steel rod which is good
The 303 is a free-cutting stainless steel. The corrosion resistance of both the 303 and 304 stainless steels is very good, and the 304 is better than the next.
The carbon content of 303 stainless steel is about ≤0.15%, and the carbon content of 304 stainless steel is about ≤0.08%.
The sulphur content of 303 stainless steel is much higher than that of 304 stainless steel, and the high sulfur content makes it easier to cut.
