What is a Stainless Steel Bar?
Our customers often use stainless steel bars. However, there are many grades of stainless steel bars. Different grades of stainless steel round bars vary in price and application. How to distinguish stainless steel bars? Walmay Metal will show you how to understand stainless steel round bars!
Stainless Steel Bar Product Details
Stainless steel round bar is a general term for round steel, stainless square bar, ss flat bar, hexagonal steel, and stainless angle bal.
A stainless steel bar is made of stainless steel ingots through hot rolling or forging. According to different classification standards, stainless steel bars can be divided into many types.
Details of stainless steel round bar
Steel bar specifications: Ф1.0MM above 250mm below Hot-rolled and forged stainless steel bars with dimensions (diameter, side length, thickness, or distance between opposite sides) not exceeding 250mm.
Stainless steel bar materials: 304, 304L, 321, 316, 316L, 310S, 630, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, duplex steel, antibacterial steel and other materials!
Surface: bright, matte
Weight calculation of stainless steel round bar
Weight calculation formula of stainless steel round bar: weight (kg) = diameter (mm) * diameter (mm) * length (m) * Density
The density of chromium-nickel steel: 0.00623
Density of chromium steel: 0.00609
Weight calculation formula of hexagonal bar: weight (kg) = opposite side (mm) * opposite side (mm) * length (m) * 0.0069
Weight calculation of stainless steel square bar
Weight calculation formula of stainless steel square bar: weight (kg) = side width (mm) * side width (mm) * length (m) * 0.00793
Stainless Steel Round Bar Production process
Ss round bar can be divided into three types according to the production process: hot rolling, forging, and cold drawing.
The specifications of hot-rolled stainless steel round bars are 5.5-250 mm.
Among them: 5.5-25 mm small bar stainless steel is mostly supplied in bundles of straight bars, and is often used as steel bars, bolts, and various mechanical parts;
Stainless steel round bars larger than 25 mm are mainly used to manufacture mechanical parts or as seamless steel pipe blanks.
Characteristics and functions of different stainless steel round bars
201 stainless steel bar: chromium-nickel-manganese austenitic stainless steel with relatively low magnetism.
202 stainless steel metal bar: chromium-nickel-manganese austenitic stainless steel with better performance than 201 stainless steel.
316 bar stainless: 316 stainless steel contains molybdenum and low carbon content.
304 stainless steel bar: has good corrosion resistance, heat resistance, low temperature strength, and mechanical properties, good hot processing properties such as stamping and bending, and no heat treatment hardening phenomenon.
304L ss steel bar: as a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to that of 304, but after welding or stress relief, its resistance to intergranular corrosion is excellent, and it can maintain good corrosion resistance without heat treatment.
310 steel round bar: high temperature resistant.
410 stainless steel bar: martensite (high-strength chromium steel), good wear resistance, poor corrosion resistance.
420 stainless steel bar: similar to Brinell high chromium steel, the earliest stainless steel.
430 stainless steel bar has good formability but poor temperature and corrosion resistance.
Application of different stainless steel round bars
304 bright bar steel: use: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196°C-700°C).
310 stainless steel bar stock: generally used in boilers and automobile exhaust pipes. Other properties are general.
302 stainless steel bar: widely used in auto parts, aviation, aerospace hardware tools, chemical industry. Specifically as follows: handicrafts, bearings, sliding flowers, medical instruments, electrical appliances, etc.
420 stainless steel bar: “blade grade” martensitic steel, also used for surgical knives, can be made very bright.
430 stainless steel bar: ferritic stainless steel, decorative, such as for car accessories.
Summarize
In general, stainless steel bar is a bar-shaped material made from stainless steel ingots through processes such as hot rolling, forging or cold drawing.
Stainless steel bars can be divided into many types, including round steel, square steel, flat steel, hexagonal steel and octagonal steel, etc. classified by shape; hot rolling, forging and cold drawing, etc. classified by production process.
