Detailed explanation of 300 series stainless steel round bar


316L stainless steel round bar: 316 stainless steel contains molybdenum and low carbon content, and its resistance to pitting corrosion in the ocean and chemical industry environment is greatly better than that of 304 stainless steel! (316L low carbon, 316N nitrogen high strength and high strength, 316F stainless steel has high sulfur content, easy to cut stainless steel.


304L stainless steel round bar: As a low-carbon 304 steel, in general, corrosion resistance is similar to 304, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent, and it can also be used without heat.


304 stainless steel round bar: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700°C).


303 stainless steel round bar: By adding a small amount of sulfur and phosphorus to make it easier to cut than 304, other properties are similar to 304.


302 stainless steel round bar: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: handicrafts, bearings, sliding flowers, medical instruments, electrical appliances, etc. Features: 302 stainless steel ball belongs to austenitic steel, which is relatively close to 304, but 302 has a higher hardness, HRC≤28, and has good rust and corrosion resistance.


301 stainless steel round bar: good ductility, used for forming products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.



Fabrication with Inconel 600

Alloy 600 can be both hot formed and cold formed using typical processes. Hot working should be performed between 1600° F and 2250° F avoiding any work between1200-1600° F because the ductility decreases in this temperature range. Welding Alloy 600 can be achieved via shielded metal-arc welding, TIG, and MIG.
