ALAS Blade Basics

• Shape: Rectangular cross-section

• Hardness: HRC 50–62

• Quality: High-precision, no burrs on cutting surfaces

• Customization: Available per your drawings

• Materials: Only H13, H13K, and LD (high-quality tool steels)

Blade Material Overview

H13 (4Cr5MoSiV1)

• Type: Hot work die steel

• Key features: Good high-temperature strength and fatigue resistance

• Used for: Hot rolled plate, iron plate, scrap metal, thick stainless steel, and high-strength alloy steel

LD (7Cr7Mo2V2Si)

• Type: Cold work die steel

• Key features: High strength, toughness, wear resistance, and no easy chipping

• Used for: High-strength steel, stainless steel, thick plates, and hard-to-cut metals (for large hydraulic shears)

Blade Material Selection Guide

1. H13 (4Cr5MoSiV1) Hot Work Tool Steel

• Hardness: HRC 50–55 (after heat treatment)

• Key features: Resists impact and high temperatures; tough core

• Suitable for: Alligator shears (≥160T)

• Cuts: Ultra-thick steel plates (≥30mm), high-hardness round steel, thick-walled pipes, and heavy materials

• Advantages: Good for heavy impact; no easy chipping/breakage; easy to use

2. H13K (Modified H13)

• Key features: Better than H13 – tougher core, more stable at high temperatures, resists fatigue

• Suitable for: Ultra-large alligator shears (≥180T)

• Cuts: Extra-thick steel plates (≥40mm), heavy alloy steel, thick seamless pipes, large structural steel

• Advantages: More impact-resistant than H13; 20–30% longer service life; best for large shears

3. LD Steel (7Cr7Mo2V2Si) Cold Work Tool Steel

• Hardness: HRC 60–64 (after heat treatment)

• Key features: Very wear-resistant; tough core; uniform hardness

• Suitable for: Medium-to-large alligator shears (100T–160T)

• Cuts: 10–30mm steel plates, thick rebar, rusted scrap, angle steel/channel steel

• Advantages: Most wear-resistant; fewer blade changes; higher work efficiency

Blade Strengthening & Heat Treatment

• Vacuum heat treatment: Replaces normal air quenching; no surface oxidation; uniform hardness

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

Material Selection Tips

• Regular crocodile/scrap shears: Use H13

• Complex scrap or harsh conditions: Use H13K

• Higher requirements: Contact us for custom material solutions
