|---|---|
304/304L: Most commonly used, containing 18% Cr and 8-10% Ni (304L has lower carbon content and is resistant to intergranular corrosion), suitable for general corrosion resistance, food,chemcial,and daily hardware.
316/316L: Containing 2-3% Mo, with stronger resistance to chloride pitting, used in marine, chemical, and medical equipment.
301/302: High manganese and low nickel, fast work hardening, commonly used for springs and high-strength wires.
321: Contains Ti, stable high-temperature structure, suitable for environments above 800 °c (such as aviation and exhaust pipes).
430/410: Ferrite/Martensite, with weak magnetism and corrosion resistance but low cost, used for non harsh environments such as decoration and fasteners.
Common range: Most stainless steel wires have a diameter between 0.05 millimeters and 6 millimeters, with fine wires up to 0.03 milimeters.
Special specifications: Special specifications:The diameter of the welding wire is mostly 0.1 millimeters to 5 millimeters, and some wires can be as thick as 32 millimeters.
Precision tolerance: The finer the wire, the smaller the tolerance, for example, a wire tolerance of 0.05 millimeters is about ± 0.002 millimeters.
Mainstream materials: Common grades include 304, 316,201, 302,etc., with 304 being the most commonly used.
Performance difference: 316 has stronger corrosion resistance and is suitable for seaside or chemical environments, while 201 has higher cost-effectiveness
