Achieves ±0.02mm flatness tolerance and ±0.01mm edge straightness tolerance. Zero-deformation assembly supports 24-hour continuous cutting without edge rolling for flawless sheet metal processing.
✅ Reversible Dual-Edge Design
Dual-edge reusable structure doubles blade service life, reduces blade replacement frequency by 36%, and effectively cuts factory annual production downtime loss by 28%.
Wide Equipment Compatibility & Social Proof
ALAS industrial shear blades are fully compatible with mainstream global shear machine brands, including Amada, Accurpress, Cincinnati, Durma and Haco, covering hydraulic, CNC and manual sheet metal shearing equipment for universal industrial applicability.
Professional Material Grade Matching System
ALAS supplies seven standardized high-performance steel grades for industrial shear blades. Each grade features exclusive optimized metallographic grain structure and fixed post-heat-treatment hardness, realizing targeted matching for cold cutting, hot shearing, precision cutting and heavy-load cutting scenarios.
9CrSi (HRC 58–60): Fine uniform grains, cost-effective for thin low-carbon steel cold cutting. 6CrW2Si (HRC 60–62): Tungsten-silicon alloy stabilized, excellent impact toughness for light hot shearing and heavy shock-loading cold cutting. Cr12MoV/SKD11 & D2 (HRC 58–62): High wear resistance, ideal for stainless steel and medium-strength steel processing. H13 (HRC 50–55): Excellent thermal fatigue resistance for cyclic high-temperature working conditions. LD Steel (HRC 58–62): Enhanced impact toughness for impact-intensive cutting tasks. ASP23/ASP60 Powder Steel (HRC 62–65+): Zero carbide segregation, maximum galling resistance to completely suppress material adhesion during ultra-heavy or precision premium stainless steel cutting.
International Steel Grade Standard Correspondence Table
All ALAS shear blade steel grades achieve one-to-one matching with global mainstream industrial standards, eliminating cross-border procurement and equipment matching risks. Consistent chemical composition and grain structure ensure stable mechanical properties and cutting precision after professional vacuum heat treatment.

Scenario-Based Material Selection Guide
ALAS adopts a rigorous “Working Condition – Material Grade – Hardness” selection logic to avoid blade chipping, adhesion and premature dulling, matching the optimal solution for different processing demands:
Ordinary Cold Cutting (Q195/Q235 Carbon Steel): 9CrSi / Cr12MoV (HRC 58–60), balanced cost and operational stability
Stainless Steel & Medium-Strength Steel Cutting: SKD11 / D2 (HRC 58–62), suppress material adhesion and ensure smooth cutting
Continuous Hot Shearing: H13 (HRC 50–55), excellent thermal fatigue resistance and high-temperature stability
Heavy-Duty Thick Plate & High-Precision Cutting: ASP23/ASP60 Powder Steel (HRC 62–65+), ultra-high wear resistance and structural stability
Standard Dimensions & Custom Manufacturing Service
ALAS covers full-size standard specifications for manual, hydraulic and CNC shearing machines, with precise metric dimensions unified globally. All blades undergo multi-stage precision grinding and stress relief treatment, with ±0.02mm flatness and ±0.01mm edge straightness for stable burr-free cutting. Unified unit standard: All specifications adopt metric mm; industry gauge units are converted synchronously (e.g., 18-gauge=1.2mm stainless steel, 14-gauge=1.9mm galvanized steel). We support exclusive custom production with an ultra-low MOQ of 1PC to adapt to non-standard equipment and personalized production lines.

Frequently Asked Questions
Q1: What quality certification documents are provided for export orders?
ALAS provides fully traceable complete export certification packages for all orders, including ISO 9001 quality system certificates, SGS material composition inspection reports, and official factory MTC (Mill Test Certificate) test reports. All technical data meets EU, US, and Southeast Asian industrial procurement standards, supporting global project bidding and inspection.
Q2: What is the production lead time for standard and custom blades?
In-stock standard blades require 3–5 working days for precision finishing and full quality inspection. Custom shear blades manufactured per customer drawings take 7–10 working days (subject to structural complexity). Priority production slots are available for urgent bulk export orders.
Q3: How to select the right blade material and avoid blade failure?
Follow ALAS standardized matching rules: 9CrSi/Cr12MoV for ordinary carbon steel, SKD11/D2 for stainless steel and medium-strength steel, H13 for hot shearing, and ASP series powder steel for heavy thick plate cutting. Always match blade hardness and material grade with actual working temperature and plate thickness to avoid equipment overload and blade damage.
Q4: What daily maintenance is required to extend blade service life?
Regularly clean cutting debris on the shear machine to avoid blade abrasion. Apply high-quality industrial lubricant to the blade edge during operation to reduce friction heat and wear. Standard daily maintenance can effectively prevent edge brittleness, chipping and premature dulling, maximizing blade service life.
Q5: How are blades packaged for international long-distance transportation?
All export blades are treated with anti-rust oil, wrapped in waterproof and dustproof film, and packed in reinforced solid wooden cases. Independent single-piece packaging effectively avoids deformation, rust and abrasion during long-distance sea and land transportation, ensuring intact product delivery.
Q6: What after-sales technical support can be provided?
We provide free lifelong remote technical guidance, including blade model selection, installation clearance calibration and daily maintenance guidance. For large-volume export orders, on-site equipment commissioning and professional team operation training are available.
