ALAS Blade Basics

• Made from high-performance H13 and H13K materials

• Rectangular cross-section, hardness: HRC50–62

• Provides precise, smooth (burr-free) cutting surfaces

• Customizable according to your drawings

H13 & H13K Material Overview

H13 Material Details

• Material Type: Hot Work Die Steel

• Key Features: Good high-temperature strength, impact resistance, toughness and hardenability

• Materials It Cuts: Hot-rolled plate, iron plate, scrap metal, thick steel (≥30mm), high-hardness round steel, thick-walled welded pipes

H13K Material Details

• Material Type: Modified Hot Work Die Steel (upgraded H13)

• Key Features: Better toughness, high-temperature stability and fatigue resistance (retains H13’s good impact resistance)

• Materials It Cuts: Extra-thick steel (≥40mm), heavy alloy steel, thick-walled seamless pipes, large structural steel, scrap yard heavy-duty cutting

How to Choose Between H13 & H13K

H13 (4Cr5MoSiV1) Hot Work Tool Steel

• Performance: HRC52–55 hardness after heat treatment; resists impact and high temperatures well

• Best for: ≥160T alligator shears; cutting thick steel (≥30mm), heavy materials

• Pros: Works well for heavy impact; prevents chipping/breakage; easy to use; mature production process

H13K (Modified H13) Hot Work Tool Steel

• Performance: Upgraded H13; keeps good impact resistance, with better toughness and stability

• Best for: ≥180T large alligator shears; extra-thick steel (≥40mm), ultra-heavy cutting

• Pros: More impact/fatigue resistant than H13; 20–30% longer service life; ideal for large shears

Blade Strengthening Process

Basic Heat Treatment Steps

1. Vacuum heat treatment (instead of air quenching): Reduces surface oxidation; ensures uniform hardness

2. Low-temperature tempering (180–220℃): Eliminates internal stress; prevents deformation/cracking; stabilizes hardness and toughness

Material Selection Tips

• Most mobile/scrap shear blades use H13

• Use H13K for complex scrap types

• For higher requirements, contact the manufacturer for material upgrades

Maximize Uptime with Quality Replacement Blades

Perfect Fit for Your Equipment

• 100% compatible with top brands (Genesis, LaBounty, NPK, Caterpillar)
