Stainless steel bar

Stainless steel bar is a long strip of metal material with excellent corrosion resistance, strength and toughness. It is widely used in machinery manufacturing, construction, chemical industry, food processing and other fields.
Classification
According to the production process:
Hot-rolled stainless steel bar: high temperature rolling, large diameter, rough surface.
Cold-rolled stainless steel bar: room temperature rolling, small diameter, smooth surface.
Forged stainless steel bar: made by forging process, with dense internal structure and high strength.
By shape: Round bar: round cross-section, the most widely used.
Square bar: square cross-section, used for special structures.
Hexagonal bar: hexagonal cross-section, commonly used for bolts, nuts, etc.
By organizational structure:
Austenitic stainless steel bar: such as 304, 316, good corrosion resistance and weldability.
Ferritic stainless steel bar: such as 430, strong magnetism, general corrosion resistance.
Martensitic stainless steel bar: such as 410, high hardness, good wear resistance.
Duplex stainless steel bar: such as 2205, which has the advantages of both austenite and ferrite.
Common grades
304: General type, good corrosion resistance and processability.
316: Contains molybdenum, has stronger corrosion resistance and is suitable for marine environment.
430: Ferritic stainless steel, low price, general corrosion resistance.
201: Partially replaces 304, with slightly worse corrosion resistance.
Application areas
Mechanical manufacturing: shaft parts, bolts, nuts, etc.
Construction: structural parts, decorative parts, etc.
Chemical equipment: pump shafts, valves, etc.
Food processing: equipment parts, containers, etc.
Medical equipment: surgical instruments, equipment parts, etc.
Processing and maintenance
Processing: turning, milling, drilling, grinding, etc.
Maintenance: Clean regularly, avoid using chlorine-containing cleaners to prevent scratches.
Market and price
Market: Global demand is large, and China is the main producer.
Price: Affected by raw materials, grades, specifications, and market supply and demand, 304 and 316 are more expensive.
Summary
Stainless steel bars are widely used in many fields due to their excellent performance and diverse shapes. Choosing the right grade and shape is crucial to performance and service life.
