Our ASTM A312 TP304 Pipe inventory is available in random lengths or cut to specific lengths to meet your exact requirements. Over the years, we have gained unique experience with pipes for different applications. We control the manufacturing process from raw material to finished product, with a constant focus on quality to meet demanding specifications.
A pipe without a seam or weld is known as Seamless Pipe. Stainless Steel 304/304L Seamless Pipes can withstand high mechanical stress and high pressure can work in high temperatures and corrosive environments. Stainless Steel Seamless Pipe is formed by drawing a solid metal billet over a piercing rod to create a hollow tube. Seamless Pipe is then processed and finished as per dimension standard ANSI B36.10 and ANSI B36.19 and B36.19M in different wall thickness and sizes ranging from SCH 5S to SCH XXS. 304/304L Seamless Pipes have varied applications in the Oil and gas, Chemical, Pharmaceutical, Fertilizer, Agro-Chemical, Aerospace, Desalination, Food and Beverage, Sugar, Distillery, Power Generation, Cement, Petroleum Refinery, mechanical and structural, food processing, etc.

Properties of 304/304L alloy
304/304L Cold Forming
Type 304/304L is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.
304/304L Hot Forming
Type 304/304L can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.
Type 304/304L is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.
Type 304/304L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308L/ER308L filler metals should be used with Type 304/304L steel, but the molybdenum-containing austenitic stainless steel filler metals may also be considered.
304/304L Heat Treatment
Annealing: Type 304/304L should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304/304L cannot be hardened by heat treatment. However, Type 304/304L can be hardened by cold working.
