2b Cold Rolled Stainless Steel Plate Sheets 0.3mm 316 304 201

The Chinese clan is the first country in the world to smelt iron and steel. Our
ancestors mastered some skills of iron smelting, steelmaking, casting and
forging and heat treatment three thousand years ago, more than 1700 years
earlier than European countries. important contributions to human progress.
Steel has become the most basic and important material for modern industrial
and agricultural production, transportation, national defense and even people's
life. At present, although various new inorganic materials and organic
synthetic materials have been greatly developed. But in terms of production
cost and wide applicability, they are far from being able to replace steel.
Therefore, the production capacity of steel is still one of the important
symbols to measure the national strength of a country. The reason why iron and
steel materials are so widely used is that iron ore deposits are concentrated,
the storage capacity is large, mining and smelting are relatively economical,
and semi-finished steel products have strong cold and hot deformation
capabilities. The finished product has excellent mechanical properties
(strength, plasticity and impact resistance) and processing properties
(cutting, welding, cold deformation, etc.). However, compared with silicic acid
materials, polymer synthetic materials and some non-ferrous metals, its biggest
disadvantage is that it is easy to lose weight due to corrosion and even
completely destroy it in the atmosphere or under various media conditions such
as acid, alkali, and salt. .
