Concept, chemical composition, mechanical properties and application of 304L stainless steel round bar
304L stainless steel concept
304L stainless steel round rod is a low-carbon stainless steel material, and its "L" stands for Low Carbon. As a variant of 304 stainless steel, it has similar corrosion resistance, heat resistance and mechanical properties, but has a lower carbon content, so it is more suitable for occasions where welding is required. 304L stainless steel round rod has been widely used in many fields because of its excellent comprehensive performance.304L stainless steel chemical composition
The chemical composition of 304L stainless steel round rod mainly includes carbon (C), silicon (Si), manganese (Mn), chromium (Cr), nickel (Ni), phosphorus (P) and sulfur (S) and other elements, the specific content is as follows:
Carbon (C) : ≤0.03%
Silicon (Si) : ≤1.0%
Manganese (Mn) : ≤2.0%
Chromium (Cr) : 18.0% ~ 20.0%
Nickel (Ni) : 8.0% ~ 12.0%
Phosphorus (P) : ≤0.045%
Sulfur (S) : ≤0.03%
Three, 304L stainless steel
304L stainless steel round rod has excellent mechanical properties, mainly including:
Yield strength (N/mm²) : ≥205
Tensile strength (MPa) : ≥520
Elongation (%) : ≥40
Section shrinkage (%) : ≥60
Hardness: HB≤187, HRB≤90, HV≤200
304L stainless steel applications
304L stainless steel round rods are widely used in many fields because of their excellent corrosion resistance and mechanical properties:
Food processing equipment: Because the 304L stainless steel round rod is extremely low in corrosiveness to food, non-toxic and harmless, it is widely used in food processing equipment, such as food containers, food processors, etc.
Medical devices: 304L stainless steel round rod has good biocompatibility and will not cause adverse reactions to the human body, so it can be used to manufacture medical devices, such as surgical instruments, implants, etc.
Chemical equipment: 304L stainless steel round rod has good resistance to acid, alkali, salt and other chemical substances, so it is widely used in the manufacture of chemical equipment, such as reactors, storage tanks and so on.
Architectural decoration: 304L stainless steel round bar has a beautiful appearance and good durability, and is widely used in architectural decoration, such as indoor and outdoor handrails, hooks, stairs, etc.
Energy field: 304L stainless steel round rod has good resistance to high temperature and high pressure environment, so it is widely used in oil, natural gas and other energy fields.
Automotive manufacturing: 304L stainless steel round rod has good strength and fatigue resistance, and is often used in automotive parts manufacturing, such as exhaust pipes.
