Datong die steel is an alloy of iron, carbon and some other elements. Stainless steel or 10.5% or more is a general term. It should be remembered that stainless steel does not mean that the steel does not rust or corrode, but it is not a chromium alloy with corrosion resistance, which is better. In addition to chromium, other metals, such as nickel, molybdenum and vanadium, can also be added to the properties of alloy steel, thus producing different grades and properties of stainless steel. Due to the purpose of the application and the different places, carefully selecting the most suitable performance, specific work efficiency and success are crucial.
Datong die steel can be roughly divided into (cold working die steel), (hot working die steel) and (plastic die steel), which are used for forging, stamping, cutting, die casting, etc. Due to the different uses and complicated working conditions of various dies, die steel should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardenability and other process properties according to the working conditions of the die. Due to different uses and complex working conditions, the performance requirements of die steel are also different.
General category of Datong steel
1. It is also known as low carbon steel. Carbon steel with carbon content from 0.10% to 0.30% is easy to accept various treatments, such as forging, welding, cutting and welding
Often used in manufacturing chains, rivets, bolts, shafts.
2. Carbon carbon content ranges from 0.30% to 0.60% in the manufacture of heavy forgings, axles, such as railways.
3. High carbon steels - commonly known as tool steels, have a carbon content from 0.60% to 1.70%, and can be quenched and tempered. From drill bit, 0.0% carbon to 0.75% carbon tap.
4. Alloy steel - steel, other metals such as chromium, nickel, tungsten, vanadium, which have several new functions. Due to the addition of various alloying elements, the fatigue properties of alloy steel are improved.
Thickness is not more than 6 mm, high efficiency blanking die. Punching die and stamping die, various scissors, inlaid blade, woodworking blade, thread rolling die and wear-resistant slider cold heading die, thermosetting resin forming mold, advanced gauge and other deep drawing and cold extrusion die.
