SUS317L Stainless Steel

SUS317L stainless steel is a kind of stainless steel alloy with very high corrosion and heat resistance, it is mainly composed of chromium, nickel, molybdenum and other elements, with excellent toughness and pitting resistance.

One. Composition

The main chemical components of SUS317L stainless steel are as follows:

Carbon (C) : ≤0.03%

Silicon (Si) : ≤1.00%

Manganese (Mn) : ≤2.00%

Phosphorus (P) : ≤0.045%

Sulfur (S) : ≤0.030%

Chromium (Cr) : 18.00%~20.00%

Nickel (Ni) : 11.00%~15.00%

Molybdenum (Mo) : 3.00%~4.00%

Two. Characteristics

1. High corrosion resistance: SUS317L stainless steel has very high corrosion resistance, especially in acid and chloride environment corrosion resistance is more prominent.

2 high temperature oxidation resistance: SUS317L stainless steel also shows good high temperature oxidation resistance, can be used in high temperature environment for a long time.

3 excellent processing performance: SUS317L stainless steel in the process of processing has good plasticity and toughness, and easy to cut and welding and other processing.

Three. Application field

Because SUS317L stainless steel has good corrosion resistance and high temperature properties, it is widely used in the following fields:

1. Chemical industry: Suitable for the manufacture of chemical reaction kettle, storage tank, pipeline and other equipment.

2. Petrochemical industry: suitable for manufacturing refineries, natural gas processing plants, fertilizer factories and other equipment.

3. Food processing industry: suitable for manufacturing food processing equipment, such as steam furnace, oven, etc.

4. Other industries: Suitable for manufacturing medical instruments, Marine equipment, aerospace equipment, etc.

Four, the applicable environment

SUS317L stainless steel material suitable for a variety of environments, especially suitable for the following

1. High temperature and high oxidation environment.

2. Seawater with high chloride ion content and salt spray environment.

3. Strong acid and alkali environments in oil fields and chemical plants.
