SUS317L Stainless Steel Round Bar ASTM 317L Uns S31703 Sts317L 1.4438 AISI 317L

ASTM 317L 022Cr19Ni13Mo3 SUS317L S31703 stainless steel round bar

has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, punching, bending, such as hot workability is good, no heat treatment hardening phenomenon.

Purpose: tableware, ambry, boiler, auto parts, medical appliances, building materials, food industry (using the temperature - 196 ° C to 700 ° C)

GENERAL PROPERTIES

Alloy 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L also provides resistance to sensitization when welded and higher creep, stress to rupture, and tensile strength at elevated temperatures. It is non-magnetic in the annealed condition but may become slightly magnetic after welding.

APPLICATIONS

Alloy 317L is commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds. Some other applications that use alloy 317L include:

• Paper and pulp handling equipment
• Chemical and petrochemical processing equipment
• Condensers in fossil and nuclear fueled power generation stations
• Food processing equipment
• Textile equipment

STANDARDS – ALLOY 317L

ASTM/ASME: UNS N08020

EURONORM: FeMi35Cr20Cu4Mo2

DIN: 2.4660

CORROSION RESISTANCE

• Demonstrates superior corrosion resistance in difficult environments including a wide range of chemicals, especially in acidic chloride environments
• Excellent resistance in applications where contamination is desired to be kept to a minimum
• Low carbon content allows 317L to be highly resistant to intergranular corrosion
• Combats the tendency to pit when in contact with phosphorus acids, chlorides, bromides, and iodides

HEAT RESISTANCE

• All chromium-nickel-molybdenum steels all have excellent resistance to oxidation
• Demonstrates a low rate of scaling in ordinary atmospheres at temperatures up to 1600-1650°F (871-899°C).
