Ordinary carbon steel (Q195, Q235): 9CrSi, Cr12MoV (cost-effective)
Medium-low hardness steel/aluminum/copper: SKD11, D2 (wear-resistant, long life)
Light stainless steel/medium-strength steel: SKD11, D2 (balanced performance)
Thick stainless steel/high-strength alloy steel: H13, LD (tough, chip-resistant)
Hot shearing/high-temperature tasks: H13, H13K (heat-resistant, anti-fatigue)
High-precision/heavy-duty shearing: Powder metallurgy steel (ASP23/ASP60) (ultra-wear-resistant, long life)
Hardness isn’t everything—balance hardness and toughness. Too hard = chipping; too soft = dulling. We help you choose the right one.
Heat treatment matters. High-quality materials need professional quenching (like our vacuum heat treatment) to work their best.
For sticky materials (stainless steel, titanium, aluminum, copper): Choose Cr12MoV or SKD11 to prevent sticking and chipping.

Mechanical blades are (special wearing parts) due to different cutting products, correct and reasonable selection of materials, heat treatment hardness, grinding accuracy, packaging requirements. Please contact us before purchase and confirm whether the blade specifications materials you need are available goods.
Our quality: All mechanical parts, tools, and molds are manufactured in-house. Upon arrival at our warehouse, products undergo rigorous inspection by a dedicated quality control department. The following is our production process:
1. Blanking-choose materials according to customer requirements.
2. Forging-Forging is mainly to increase the density of the material.
3 .Annealing-to lower the temperature for processing.
4 .Finishing ---- mainly processing materials.
5 .Inspection ---- Inspect whether the product is consistent with the drawing sample.
6.Quenching ---- Improve the hardness of molded products and materials.
7 .Annealing-In order to increase the wear resistance of the product, it must be annealed for a long time to prevent the blade from breaking
8 .Tempering-mainly the parallelism of the tempering products for processing.
9 .Rough grinding ---- rough grinding the surface of the product.
10.Precision grinding ---- Super-precision grinding and mirror grinding to improve the accuracy and parallelism of the product.
11. Inspection-Let unqualified products refuse to flow into the market.
12 .Packing ---- Pack differently according to different products.
