●440F small tolerance (can reach half wire) high precision, smooth surface, no skin, roll marks and other phenomena.
●Roll out for the straight state, small deviation, to ensure straightness (generally 3 meters 1MM), will not appear "chain knife bending" phenomenon.
●For automatic lathes.
●Martensitic stainless steels have the properties of hardening through quenching, as do ordinary alloy steels.
●By selecting the grade and heat treatment conditions to obtain a large range of different mechanical properties.
●Widely used in the production of electronic components.
●Precision welded pipe and other fields to replace imported high-precision stainless steel special materials.
