Stainless steel sheet metal is a flat long strip of steel, usually made of austenitic stainless steel (such as 304, 316) or martensitic stainless steel (such as 410, 420).
stainless steel sheet metal has excellent corrosion resistance, high strength and good processing performance.
It is widely used in architectural decoration, food processing, chemical equipment, medical equipment and other fields.
The chemical composition of stainless steel is the basis of its excellent performance. (Take 304, 316, 410, 430 as an example)

Stainless steel
Martensitic stainless steel: This type of stainless steel usually has a higher carbon content, which gives it higher strength and hardness. Common martensitic stainless steels include 410, 420, 430 and 440.
Ferritic stainless steel: The main components are iron and chromium, and the chromium content is usually greater than 14%. Common ferritic stainless steels include types such as 430, which are suitable for manufacturing products such as home appliances and kitchenware.
Austenitic stainless steel: This is the most widely used type of stainless steel, with good plasticity, toughness and corrosion resistance. Austenitic stainless steel is divided into chromium-nickel stainless steel and chromium-manganese stainless steel, and common types include 304 and 316.
Duplex stainless steel: This type of stainless steel has the organizational characteristics of both austenite and ferrite, with high strength and good toughness, while maintaining good corrosion resistance.
316 stainless steel
The best grade of stainless steel is 316 stainless steel.
316 stainless steel adds molybdenum to 304 stainless steel, which has better corrosion resistance and is especially suitable for harsh conditions such as marine environment, high temperature and high pressure.
It is more corrosion-resistant than 304 stainless steel, especially for salt corrosion, which is more likely to occur in stainless steel kitchenware. 316 has stronger corrosion resistance than 304.
We provide a variety of surface treatment methods such as bright annealing, brushing, sandblasting and polishing.
