Product Description

420 stainless steel plate is a martensitic stainless steel with higher carbon content than grade 410, designed for applications requiring excellent hardness, wear resistance, and moderate corrosion resistance. It can be heat-treated to achieve a hardness of up to 50 HRC, making it the hardest among the 12% chromium grades.

Grade 420 stainless steel is widely used in cutlery, surgical instruments, pump shafts, valve components, bearings, and plastic molding tools. Its combination of high strength, good polishability, and cost-effectiveness makes it a popular choice across multiple industries.

    Precision 301 304 316 430 Cold Rolled Stainless Steel Strip 2B BA No.4 Finish
    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
