Metal Shear Knives
T10, 9CrSi, Cr12MoV, and H13 straight guillotine shear blades for hydraulic and mechanical plate shears—surface-ground to ±0.05mm full-length parallelism for burr-free, straight-edge shearing of mild steel, stainless plate, and hot-rolled billets. Single-piece length to 6000mm; 1, 2, or 4 cutting edges available. Alloy grade matched to your shear tonnage and material: cold shearing (57–59 HRC), stainless/alloy plate (58–62 HRC), or hot billet shearing (H13/LD, high-temperature resistant). OEM matching dimensions for TRUMPF, AMADA, BYSTRONIC, and Durma hydraulic guillotines.

Engineering Advantages
Cold-Rolled & Mild Steel Shearing
Forged from T8/T10 carbon tool steel and hardened to 57-59 HRC. An incredibly cost-effective solution for cutting standard A3 plates, mild steel, and general scrap recycling without compromising edge integrity.
Stainless & Medium Plate Shearing
Utilizing premium low-alloy steels like 9CrSi, 6CrW2Si, and Cr12MoV. Deep-hardened to 58-62 HRC to withstand extreme abrasive wear when shearing stainless steel and thicker alloy plates.
Hot-Rolled Billet Shearing
Engineered for heavy steel mills. Made from H13 and LD alloys that retain their hardness and resist annealing at extreme temperatures, perfect for hot shearing billets and heavy slabs.

Product FAQs & Buying Guidance
Technical FAQs
01Which alloy should I use for shearing 304 stainless steel and thick alloy plate?+−
We recommend 9CrSi or Cr12MoV (D2 equivalent) for stainless steel (304, 316L, 430, 2205 duplex) and high-strength plates like Hardox 400 or Domex 700. Cr12MoV's high chromium-carbide matrix withstands the severe work-hardening wear imposed by austenitic stainless. For standard mild steel or scrap bale cutting, T10 or 65Mn at HRC 57–59 provides maximum toughness at the lowest cost.
02What edge profile minimizes burrs when shearing high-tensile steel plates?+−
The edge profile that minimizes burr on high-tensile plate (Hardox, Domex, austenitic stainless) is a precision-ground acute bevel with strict full-length parallelism control. The critical factor is contact uniformity: uneven blade-to-blade contact concentrates shear force at one end, producing the compressive rollover and tearing burr characteristic of high-work-hardening steels. Our standard tolerance is ±0.05mm parallelism over 1000mm; premium ±0.02mm is specified for stainless, Hardox 400, and aerospace aluminium applications.
03Can you manufacture blades to match my TRUMPF, AMADA, or Durma guillotine exactly?+−
Yes. We carry OEM-matching dimensions in standard stock for TRUMPF TrumaBend, AMADA QC-67Y, BYSTRONIC Xpert, Durma AD, Haco Atlantic, and Zhiyi QC11Y/K platforms. Single-piece blades up to 6000mm, multi-segment designs for longer tables, and single, double, or quad-edge profiles are all available. Custom lengths and back-edge profiles are manufactured to drawing within 15 working days.
04Can Sureay manufacture replacement shear blades for obsolete machines where OEM spares are discontinued?+−
Yes. For obsolete shear models — Haco, Pacific, older Amada and Trumpf variants — we work from customer-supplied drawings or physical blade samples. A dimensional survey template is available on request for accurate measurement of blade profile, mounting holes, and back-edge configuration. Custom production lead time is 15 working days from dimensional sign-off.
05How do double-edge reversible blades reduce my annual shear tooling cost versus single-edge options?+−
A double-edge (reversible) blade provides two independent cutting faces from a single blade body. When edge 1 shows wear, loosen the mounting bolts, flip the blade 180°, retorque — under 10 minutes per blade. This halves blade change events per year and reduces per-cut tooling cost by up to 40% versus single-edge alternatives. Available on all standard guillotine shear configurations up to 4000mm table length.
Why Choose Sureay
01Are you a trading company or a direct manufacturer?+−
We are a 100% direct OEM manufacturer established in 2008. When you buy from Sureay, you bypass middleman markups and communicate directly with the engineers who forge and grind your blades.
02What makes Sureay's heat treatment different from cheaper alternatives?+−
Unlike standard quenching, every Sureay blade undergoes deep cryogenic treatment after vacuum hardening. This transforms retained austenite into martensite, boosting wear resistance by up to 40% and ensuring uniform hardness across the entire cutting edge.
03Do you ship globally and how long does it take?+−
Yes, we export to over 50 countries. Standard OEM replacement blades typically ship within 48 hours. Custom profiles take 10–15 working days. We partner directly with DHL, FedEx, and international sea freight forwarders for reliable door-to-door delivery.
04What quality certifications does Sureay hold, and can you provide material test reports?+−
Sureay is ISO 9001:2015 certified. Every shipment includes a Rockwell HRC hardness test report, a dimensional inspection record, and a heat treatment batch certificate. For OEM qualification, full CMM dimensional reports and steel mill certificates are available on request.
05Can we trial a sample set before committing to a full production order?+−
Yes. We offer sample sets (typically 2–5 blades) for machine fit verification and edge life testing. Standard sample lead time is 5–7 working days. For custom profiles, dimensional sign-off samples are produced before full production commences — no tooling commitment until fit is confirmed.
