Key features: Good high-temperature strength and resistance to heat damage
What it cuts: Hot rolled plate, iron plate, medium/thick plate, scrap metal, strip steel, high-strength alloy steel, thick stainless steel
Key features: High strength, tough, wear-resistant, not easy to chip, good overall performance
What it cuts: High-strength steel, stainless steel, thick plate, hard-to-cut metals (for large hydraulic and heavy CNC shears)
Hardness: HRC 52–55 after heat treatment
Performance: Resists impact, high temperature, and damage; tough core
Suitable for: Shears ≥160T; cuts ultra-thick steel (≥30mm), high-hardness round steel, alloy steel, thick-walled welded pipes
Pros: Good for heavy impact, no chipping/breakage, easy to use, mature production process
Performance: Better than H13 – retains impact resistance, tougher core, more stable at high temperatures, longer service life
Suitable for: Shears ≥180T; cuts extra-thick steel (≥40mm), heavy alloy steel, thick-walled seamless pipes, large structural steel, scrap yards (continuous heavy cutting)
Pros: More impact-resistant than H13; 20–30% longer service life; best for ultra-large shears
Hardness: HRC 60–64 after heat treatment
Performance: Very wear-resistant, tough core, uniform hardness
Suitable for: Shears 100T–160T; cuts 10–30mm steel plates, thick rebar, rusty scrap steel, angle steel/channel steel
Pros: Most wear-resistant; fewer blade changes; faster production
Vacuum heat treatment (instead of ordinary heating): Reduces surface damage, ensures uniform hardness
Low-temperature tempering (180–220℃) after heating: Eliminates internal stress, prevents deformation/cracking, stabilizes hardness and toughness
Standard blades: Use H13
Complex scrap: Use H13K
Higher requirements: Contact the manufacturer for better materials
Quality steel: H13, 6CrW2Si – vacuum-hardened to HRC 52–58, tough, no cracking
Fits major brands: McIntyre, Kajman, Guidetti, GQ series – precise fit, clean cuts
Saves time/money: Less machine strain, better material separation, factory-direct prices
