Among steel products, cold-rolled sheets have very strict requirements for surface quality. Surface defects are the most significant quality issues for cold-rolled sheets. Once surface defects occur in cold-rolled sheets, they will seriously affect the quality and performance of subsequent deep-processed products. For a period of time, the cold-rolled products of the First Steel Rolling…
With the development of information technology and computer network technology, the mold manufacturing industry has entered a new era of globalization, and competition is becoming increasingly fierce. The market’s demands for product quality, production processes, and time to market are also getting higher and higher. Under such circumstances, cost control, production efficiency, and technical factors…
The differences between alloy steel and carbon steelI. Definition of Steel:Steel can be classified into carbon steel and alloy steel based on its carbon content and the content of alloying elements. Steel is generally referred to as an iron-carbon alloy or a solid solution of carbon in crystalline iron.Steel refers to steel that, in addition…

Die steel can be roughly classified into three categories: cold working die steel, hot working die steel and plastic die steel, which are used in casting, stamping, cutting, die casting, etc. Due to the different uses and complex working conditions of various dies, die steel should have high hardness, strength, wear resistance, sufficient toughness, as…
Tungsten steel has a series of excellent properties such as high hardness, good wear resistance, high strength and durability, heat resistance, and corrosion resistance. Particularly, its high hardness and wear resistance remain unchanged even at 500℃, and it still maintains high hardness at 1000℃.Tungsten steel, also known as hard alloy, is a sintered composite material…
Tensile strength (MPa) 620 MIN Yield strength (MPa) 310 MIN Elongation (%) 30 MIN Area reduction (%) 40 MIN The density of 316L stainless steel is 8.03 g/cm³, which is the standard value for austenitic stainless steel. 1. 316L is added with Mo (2-3%) to enhance its resistance to pitting corrosion, high-temperature creep strength. 2….
In the second half of 2025, the global stainless steel market, under the dual influences of policies and trade, presented a new and complex situation.The United States has imposed a maximum 50% tariff on imported stainless steel, which has led to the suspension or postponement of orders by one-third of enterprises worldwide, and more than…
