Date:2022-10-22View:320Tags:welded pipes,Stainless Steel Pipe,seamless tubes

TYPE 304 / 304L STAINLESS PIPE

An austenitic chromium-nickel stainless steel

General purpose corrosion resistance

Non-magnetic except when cold worked


TYPE 304H STAINLESS PIPE

Higher carbon than Type 304 for better high temperature creep properties

Corrosion resistance same as Type 304

Used in high temperature over 1000 degrees F


TYPE 309S STAINLESS STEEL PIPE

Superior heat resisting austenitic stainless steel

Good for continuous exposure to 2000 degrees F

Slightly better corrosion resistance than Type 304


TYPE 310S STAINLESS STEEL PIPE

Superior heat resisting austenitic stainless steel

Good for continuous exposure to 2100 degrees F

General corrosion resistance better than Type 304 and 309


TYPE 316 / 316L STAINLESS STEEL PIPE

An austenitic chromium-nickel stainless steel

Improved corrosion and heat resistance

Improved corrosion resistance to chlorides


TYPE 317L STAINLESS STEEL PIPE

An austenitic chromium-nickel molybdenum stainless steel

Improved chloride pitting resistance over Type 316

Used in Chemical, petroleum, pulp and paper industries


TYPE 321 / 321H STAINLESS STEEL PIPE

An austenitic stainless steel that contains titanium stabilizing elements

Improved intergranular corrosion resistance

Excellent for high temperature service in carbide precipitation range


TYPE 347 / 347H STAINLESS STEEL PIPE

An austenitic stainless that contains columbium stabilizing elements

Improved intergranular corrosion resistance

Excellent for high temperature service in carbide precipitation range


TYPE 410 STAINLESS STEEL PIPE

An martensitic stainless steel with high mechanical properties

Resist abrasion and wear better than most 300 series stainless steel

Fair resistance to general corrosion and oxidation


TYPE 446 STAINLESS STEEL PIPE

An high chromium ferritic stainless steel

Excellent high temperature resistance to oxidation and corrosion

Commonly used in high temperature applications


904L STAINLESS STEEL PIPE

An austenitic stainless steel with low carbon content

Good resistance to pitting and crevice corrosion

Resistance to general corrosion in reducing acids


DUPLEX 2205 STAINLESS STEEL PIPE

Dual-phase, 45% ferritic and 55% austenitic stainless steel

Good strength, toughness and corrosion resistance

Resists chloride stress corrosion cracking


254 SMO STAINLESS STEEL PIPE

An austenitic stainless steel with a high Molybdenum content

High resistance to pitting and crevice and general corrosion

Very high resistance to chloride stress corrosion cracking
