Some people often confused tool steels with mold steels because their definitions seem similar. Generalized tool steels include mold steels, which have some common characteristics, such as the need to bear great local pressure and strong wear, how to achieve the balance of toughness and wear resistance is their biggest contradiction. In a narrow sense,…
Cold work tool steels are the main raw materials for tools such as gauge, drill steel and punch press, as well as dies such as stamping, forging, rolling and rolling. In cutting, bending, stamping, compression and other processes, the mold is subjected to high surface pressure and impact load, most of the mold due to…
Mold steels can be divided into cold work mold steels, hot work mold steels and plastic mold steels. Plastic mold steel has accounted for more than 50% of the consumption of mold steel, has been used for the manufacture of plastic mold materials with different requirements. Therefore, many countries have formed their own codes of…
High strength steel ASTM A519 Gr.4130 is a medium carbon modulated Cr-Mo steel with excellent yield strength, tensile strength and notch toughness. The material offers a high carbon content, and the appropriate addition of Cr, Mo and other elements can improve its hardenability and anti-tampering softening tendency, which has been widely used in Marine high-pressure…
Chromoly steel 4130 has excellent strength and toughness, good hardenability and weldability, is a commonly used steel pipe for structural and mechanical purposes. It is mainly used for quenching and tempering parts with large cross-sections and working under high-stress conditions in the machinery manufacturing industry such as shafts, spindles, high load steering wheels, bolts, studs,…
Free-machining steel also referred to as Free-cutting steel or Automatic Steel, is the alloy steel by added elements such as sulfur, lead, calcium, selenium, tellurium, and bismuth to lubricate the cutting tool, reducing the cutting resistance of the steel, thereby reducing the surface roughness of the workpiece and increasing the cutting speed and prolonging the…
