What is the difference between 304 stainless steel and 304L stainless steel?
304 stainless steel
Performance introduction：304 stainless steel is the most common steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot processing is good, no heat treatment hardening phenomenon (non-magnetic, then use the temperature -196℃ ~ 800℃).
Scope of application：Household goods (Class 1 and 2 tableware, cabinets, indoor plumbing, water heater, boiler, bathtub)
Auto parts (windshield wipers, mufflers, molding products)
Medical equipment, building materials, chemicals, food industry, agriculture, Marine components
304L stainless steel (L is low carbon)
Performance introduction：As a low-carbon 304 steel, in the general state, its corrosion resistance is similar to that of 304, but after welding or stress relief, its grain boundary corrosion resistance is excellent; In the absence of heat treatment, it can also maintain good corrosion resistance, and the use temperature is -196℃ ~ 800℃.
Scope of application：It is used in chemical, coal and petroleum industry with high grain boundary corrosion resistance, heat resistant parts of building materials and parts with difficulty in heat treatment.
