What causes inconsistent hardness on finished blades, and how does ALAS prevent it?

Inconsistent hardness in the industrial knife industry is typically caused by unstable heating temperatures, uneven cooling rates during quenching, insufficient tempering cycles, or raw material carbide segregation.To guarantee absolute consistency, ALAS implements a rigorous full-process digital temperature monitoring system coupled with a triple-tempering protocol . This guarantees that our finished blades maintain an extremely tight uniform hardness deviation within ±1 to ±2 HRC across the entire batch.

What are Nitriding and TiN coatings, and what specific benefits do they bring to blades?

Nitriding Treatment : This process diffuses nitrogen into the steel surface to form an ultra-hard, wear-resistant layer. It is engineered to exponentially extend blade service life in highly abrasive cutting applications . TiN (Titanium Nitride) Coating : This premium PVD surface coating dramatically minimizes the coefficient of friction, effectively preventing workpiece adhesion (galling) . It ensures cleaner cuts with fewer burrs and offers superior corrosion resistance, making it ideal for high-speed, continuous industrial shearing scenarios .

What is vacuum heat treatment, and why do you apply it to your cutting blades?

Vacuum heat treatment is an advanced thermal processing technique conducted in an oxygen-free, high-vacuum furnace. Compared to conventional atmosphere furnaces, vacuum quenching completely eliminates surface oxidation and decarburization . This process ensures uniform core-to-surface hardness , drastically minimizes internal residual stresses, and significantly reduces the risks of micro-cracking, edge chipping, and premature wear during heavy-duty operations
