Metal Shearing Blades: Frequently Asked Questions
Q: Which steel grade suits stainless steel shearing best?
Thin stainless steel sheets adopt D2 (Cr12MoV) material.
Thick stainless steel plates apply H13 steel.
D2 features high carbon and chromium content, boasting outstanding hardness and wear resistance.
H13 owns solid toughness, thermal stability and impact resistance, effectively avoiding edge chipping and fracture when cutting thick stainless steel.
Q: Do you provide blades for hot shearing operation?
We have dedicated blades applicable to hot shearing scenarios including steel mill production.
H13 and H13K tool steel serve as core raw materials.
Such steel maintains steady hardness and internal structure under high temperature, extending service lifespan in hot working environment.
Q: What guarantees smooth cuts without burrs?
Sharp cutting edges and precise parallelism are two core factors.
All blades undergo CNC grinding process, with full-length parallelism controlled within ±0.02mm tolerance.
High precision enables narrow blade clearance, producing neat cuts and cutting down subsequent deburring workload and expenditure.
Q: Can the blades be used reversibly on four sides?
Most rectangular shear blades come with four finely ground usable edges.
Users can flip and reuse the blade four times before professional regrinding.
Its usable life is four times longer than single-edge cutting blades.
Q: Custom blades for special and outdated machine models available?
Custom processing for non-standard and old equipment blades is supported.
Conventional sizes matching Amada, LVD, Accurpress mainstream brands are in stock.
Submit technical drawings or complete dimension data including length, width, thickness and bolt hole position for customization.
Products will be manufactured to fit your equipment precisely.
Q: What is the maximum single-piece blade production length?
Integral shearing blades can be processed up to 6000mm in length.
Ideal matching part for large hydraulic shears used in shipbuilding and heavy engineering construction.
Q: What is the proper regrinding cycle for shear blades?
Service material directly decides regrinding frequency.
Two obvious signs indicate blade regrinding necessity: rolled workpiece cutting edge, increased cutting resistance of equipment.
Daily blade maintenance is essential to prevent overheating and irreversible hardness loss.
Q: How to stop blade cracking under heavy load shearing?
Vacuum heat treatment is adopted to achieve uniform overall hardening.
Common flame hardening only strengthens blade surface, while integral hardening greatly elevates impact durability.
Blades stay intact without crack or breakage under heavy impact cutting conditions.
