Stainless Steel Plate Cutting Machine Blades Material H13

Hydraulic shearing machine manufacturers usually choose 6CrW2Si as the material for the shearing blades to save costs. However, it is used for the shearing of medium and thick plates. Especially for metal materials with high shear strength, such as stainless steel, 6CrW2Si tools often need to be sharpened or even replaced after one to two years of use. H13 is a better choice.

1. What Is H13 Material?

H13 electro-slag material, in simple terms, is H13 steel optimized by the electro-slag remelting process. H13 steel is a classic in hot-working die steel. Electroslag remelting greatly reduces impurities and defects in steel, soars purity, and directly maximize performance.

Unique Composition Revealed

H13 electro slag material is similar to ordinary H13 steel in composition. Carbon (C) content of 0.32% - 0.45% lays the foundation for strength and hardness; chromium (Cr) 4.75% - 5.50% improves hardenability and oxidation resistance; molybdenum (Mo) 1.10% - 1.75% enhances thermal strength and tempering stability; silicon (Si) 0.80% - 1.20% further enhances strength; vanadium (V) 0.80% - 1.20% is responsible for grain refinement and increased wear resistance.

Superb Performance Advantages

Ultra-high purity: After electro-slag remelting, the impurities of H13 electro-slag material are almost zero, and the organizational structure is uniform and dense. When used, the probability of cracks is greatly reduced, and the reliability of the mold is greatly increased.

Excellent Thermal Stability

At high temperatures, the hardness and strength of H13 electroslag materials are stable online. It can easily cope with high temperatures, high pressure of die casting, and frequent thermal shock of hot forging, and it can work continuously and stably to ensure the accuracy of the mold.

Good Toughness and Fatigue Resistance

This material has high strength and good toughness. When the hot working die is subjected to impact load, it can effectively resist crack initiation and expansion, has good thermal fatigue resistance, can withstand more thermal cycles, and reduces the frequency of maintenance and replacement.

2. H13 Material Solves The Pain Points of Enterprises

Die-Casting Mold

When producing aluminum alloy and magnesium alloy die-casting parts such as automobile engine cylinder blocks, cylinder heads, and wheels, H13 electro slag material can be called a "savior". In the past, enterprises die-cast complex parts, due to poor mold material performance, large part size deviation, rough surface, and high scrap rate. H13 electro slag material can accurately shape complex structures, die-cast parts have high dimensional accuracy and a smooth surface, meet the strict quality requirements of the automotive industry, greatly reduce scrap rate, and save costs.

Hot Forging Mold

When forging large mechanical parts and aerospace parts, H13 electro slag material is fully demonstrated. When forging in enterprises, ordinary material molds are easy to deform and wear quickly under huge impact force and high temperature, and the forging size is inaccurate, and the quality is unstable. With its powerful performance, H13 electroslag material can withstand pressure and high temperature steadily, ensuring the accurate shape and size of forgings, helping enterprises improve product quality and establish a foothold in the field of high-end manufacturing.

Hot Extrusion Die

When extruding copper alloy and aluminum alloy profiles, H13 electro-slag material performs well. In the past, due to uneven mold materials, the surface of the profiles was uneven, and the wall thickness was inconsistent when they were extruded. H13 electro-slag material allows the material to be extruded evenly, ensuring the quality and surface flatness of the profiles. The profiles produced are widely used in the construction, electronics, and other industries, improving the competitiveness of corporate products.
