Applicable to: High-end precision shearing operations and working conditions with extremely high requirements for wear resistance and service life.

Simple Guide for Blade Material Selection

Shearing ordinary carbon steel (Q195, Q235, etc.): Prioritize 9CrSi and Cr12MoV, with high cost performance, suitable for basic shearing needs of all thicknesses;

Shearing medium and low hardness steel / aluminum and copper plates (45# steel, 40Cr, aluminum plate, copper plate, brass / red copper plate, etc.): Choose SKD11 and D2, with wear resistance, anti-deformation and long service life;

Shearing light stainless steel and medium strength steel: Choose SKD11 and D2, which balance wear resistance and chipping resistance with stable shearing performance;

Shearing stainless steel thick plate, high strength alloy steel / cold shearing hard-to-shear thick plate: Choose H13 and LD, with high strength, excellent toughness and extremely strong chipping resistance;

Hot shearing strip steel, hot shearing thick plate / high temperature working condition shearing: Special H13 and H13K materials, resistant to high temperature softening, with excellent thermal fatigue and impact resistance;

High-end precision shearing, high-frequency heavy shearing / working conditions with high requirements for wear resistance and long service life: Choose powder metallurgy steel (ASP23/ASP60, etc.), with ultimate wear resistance and shearing precision and the longest service life.

Notes

Higher blade hardness is not always better, and hardness and toughness need to be balanced: Excessively high hardness is prone to chipping, while excessively low hardness is prone to passivation. It is necessary to select reasonably according to the shearing material and operation load;

For the same material, the heat treatment process directly affects the performance: High-quality materials need to be matched with professional quenching and tempering processes to give full play to their advantages such as wear resistance and toughness;

For sticky knife materials (such as Stainless steel, titanium alloy, aluminum, copper and its alloys): Prioritize Cr12MoV and SKD11, which can effectively prevent knife sticking and chipping, and improve shearing efficiency and quality.
