Here is a collection of the more commonly used Stainless steel bar material introduction, hoping to help more friends know about stainless steel rods.
Stainless steel bar material introduction
201 stainless steel bar:
It is a chromium-nickel-manganese austenitic stainless steel with low magnetic properties.
202 stainless steel bar:
It belongs to chrome-nickel-manganese austenitic stainless steel and has better performance than 201 stainless steel.
301 stainless steel bar:
Good ductility for molding products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
302 stainless steel bar:
It belongs to austenitic steel and is close to 304, but the hardness of 302 is higher, HRC≤28, and it has good rust and corrosion resistance.
302 stainless steel rods are widely used in auto parts, aviation, aerospace hardware tools, and chemicals. The details are as follows: crafts, bearings, sliding flowers, medical equipment, electrical appliances, etc. Characteristics: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC ≤ 28, with good rust and corrosion resistance.
303 stainless steel bar:
It is easier to cut than 304 by adding a small amount of sulfur and phosphorus, and other properties are similar to those of 304.
304 stainless steel 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 equipment, building materials, food industry (use temperature -196 ° C -700 ° C).
304L stainless steel bar:
As a low-carbon 304 steel, in general, the corrosion resistance is similar to that of 304, but after welding or after stress relief, it has excellent resistance to intergranular corrosion and maintains good corrosion resistance without heat treatment. Sex.
310 stainless steel bar:
The main features are: high temperature resistance, generally used in the boiler, car exhaust pipe. Other properties are general.
316L stainless steel bar:
316 stainless steel contains molybdenum and has a low carbon content, which is much better than 304 stainless steel in marine and chemical industrial environments. (316L low carbon, 316N high nitrogen, high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel.
408 stainless steel bar:
Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409 stainless steel bar:
The cheapest model (British and American), usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
410 stainless steel bar:
It belongs to martensite (high-strength chrome steel), has good wear resistance and poor corrosion resistance.
416 stainless steel bar:
The addition of sulfur improves the processing properties of the material.
420 stainless steel bar:
“Grade grade” martensitic steel, similar to the earliest stainless steel of Brinell high chromium steel. Also used for surgical knives, it can be done very brightly.
430 stainless steel bar:
Ferritic stainless steel, for decoration, for example for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
440 stainless steel bar:
High-strength cutting tool steel, slightly higher in carbon content, can obtain higher yield strength after proper heat treatment, and the hardness can reach 58HRC, which is among the hardest stainless steel. The most common application example is the “razor blade.” There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).
