I.12713 corresponds to what steel in the country
1. This kind of steel is easy to form white spots, and it is necessary to strictly control the smelting process and the cooling system after forging and rolling. 5CRNimo Approximate Composition Foreign steel grades: American L6 (AISI), Japan SKT4 (JIS), Japan GFA (Datong), Japan DM (Hitachi), Germany 2713 (W-NR), France 55NICRMov7 (NF).
2. SKT4 steel is a Japanese standard grade, which is a typical general steel for hot and cold molds.
The hardenability, tempering, wear resistance and compressive resistance of the steel rank first among the chromium-tungsten-silicon impact-resistant tool steels, but the large and medium section steels have a tendency to appear ribbon carbide segregation, so the toughness is poor, and the decarburization sensitivity of the steel is strong when heated, and it is difficult to control the quenching deformation.
3. SKD61 spot resources are complete in specifications, and large quantities can be delivered SKD61 What materials are available in China Shanghai Benlai Metal is not only a first-class supplier of SKD61 die steel, but also a stockist of corrosion-resistant alloys and special die steels.
4. American grade L6, German grade 2713, Japanese grade SKT4, Chinese grade 5CR5NMO. Its steel characteristics: heat-resistant and wear-resistant forging die steel. Uses: Large forging dies with better toughness than 5CrMnmo. Plastic mold steel: American grade P20, German grade 2311, Swedish grade 618, Japanese grade PDS-3, Chinese grade 3CR2MO.
2. DIN 1What is the domestic material corresponding to 2714
1. DIN 2714 die steel is improved on the basis of 2344234. The advantages of 234 are retained, and better heat crack resistance is obtained.
271 steel has good toughness, ductility and crack resistance. Chromium is added to improve the fatigue resistance and toughness of the mold.
2. What is the domestic material corresponding to DIN 271?DIN 2714 mould steel is an improved version of the 2344234. The advantages of 234 are retained, and better heat crack resistance is obtained. 271 steel has good toughness, ductility and crack resistance.
3. At present, there is no correspondence with China's materials. Standard: DIN1735 Grade: 56nicrmov2714 die steel tempering stress relief temperature 2714 (56nicrmov hot work die steel 2714 steel has a high CR content and high hardenability 2714 die steel tempering stress relief temperature, quenching time cooling can obtain martensitic structure.
Standard grades are: DIN EN ISO 495ASTM A681, etc. General Trend: 2714 is a commonly used die steel, which is used in metal processing, mold manufacturing and other fields, and is expected to continue to grow in the future.
Corresponding to domestic materials, what is the hardness of 2714 Forging, softening annealing, hardening, tempering 1100-850 650-700 830-870 300-600 Purity: according to ASTM E45 Method A, A sulfide 5, B oxide, C silicate and D spherical oxide 1 each or DIN 50602-K1 1 or according to customer requirements.
