Wholesale Direct Sales DIN 1.1542 /GB 5CrW2Si/ ASTM S1 Steel Round Bar
1: DIN 1.1542 steel introduction
1.2542 steel is a multi-purpose alloy structural steel from Suster Steels Germany with non-deforming wear-resistant properties, appropriate hardness and good toughness. The hardness of the steel can be adjusted to different application scenarios by means of different heat treatments. It is widely used in stamping, shearing and hot forging.

| Application | 1.1542 is suitable for cold stamping processing of blanking dies and punches. The abrasion and impact resistance of this steel makes it ideal for applications that are subjected to a high level of impact during the stamping process.for shearing dies and cutting tools. 1.2542 steel's good toughness and appropriate hardness enable it to maintain stable performance during the shearing and cutting process.For applications such as hot forging die punches. The alloy structure and wear resistance of this steel enables it to withstand hot forging processes at high temperatures and pressures. | |
6: Heat Treatment
High temperature tempering softening:
The 1.2542 steel billet will be subjected to high temperature tempering softening treatment, the specification of the temperature of 730~750 ºC, the time is 8~10 hours. After softening treatment, the hardness of the steel can be reduced to less than 228 HBS. this treatment can be used for the softening of tungsten-containing die steel billets
Quenching:
The specifications for quenching 1.2542 steel are quenching temperature 860~900ºC and cooling medium 20~40ºC oil. After quenching treatment, the hardness of the steel can reach more than 55HRC.
Tempering:
1.2542 steel tempering specifications for the tempering temperature of 200 ~ 250 ºC, heating medium for oil or molten alkali, cooling medium for air. After tempering treatment, the hardness of steel can be maintained between 53~58 HRC.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
Hunan Qilu Industrial Co., Ltd has the capacity to forge round steel, steel flat, square steel, module, shaft and roller, etc. The main specifications of the products include Φ80-1000mm forging materials and 80-1200mm square billets and which the maximum piece weight can reach 50T.
