Product Introduction

ASTM A312 TP304L is a standard specification for seamless, straight-seam welded, and heavily cold worked austenitic stainless steel pipes. TP304L is the low carbon version of TP304, which is the most commonly used stainless steel grade for piping applications.

The TP304L seamless pipe is made from a solid round billet, which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. It is then further processed through cold drawing or cold rolling to achieve the desired dimensions and surface finish.

The TP304L seamless pipe is commonly used in various industries such as chemical, petrochemical, food processing, pharmaceutical, and power generation. It is known for its excellent corrosion resistance, high temperature strength, and good mechanical properties.

The ASTM A312 TP304L seamless pipe is available in various sizes and schedules, ranging from 1/8" to 24" in nominal diameter and from SCH 5S to SCH XXS in wall thickness. It can be supplied in random lengths or cut-to-length as per customer requirements.

The chemical composition of ASTM A312 TP304L stainless steel includes elements such as chromium, nickel, manganese, silicon, carbon, phosphorus, sulfur, and nitrogen. The composition is controlled within specified limits to ensure the desired properties of the material.

The mechanical properties of TP304L seamless pipe include tensile strength, yield strength, elongation, and hardness. These properties are tested and specified in accordance with ASTM A312 requirements.

In addition to the standard ASTM A312 TP304L seamless pipe, there are also other variations available, such as welded pipe (ASTM A358 TP304L) and seamless and welded pipe for high-temperature service (ASTM A312 TP304H).
