(Ultra-high rust-proof stainless steel AA)
(hardened HRC54 ° ± 2 ° Section)

Ultra-high anti-rust & high wear-resistant , high hardness, high impact, high toughness stainless steel, with excellent anti-rust capability, corrosion resistance, wear resistance (high hardness) performance and ideal impact resistance.. Its excellent corrosion resistance is comparable to TYPE 304 Stainless steel; and its rust resistance is closer to alloy for surgical implant. Unmarked, with 5% Neutral salt spray test (ASTM B117), it doesn’t rust after 1000 hours. Wide range of applications, quite good and stable quality, which can be used to produce extremely complex, high-precision shank shapes and profile ultra-sharp edge structures.
