Austenitic Stainless Steel ASTM A312 TP304 1.4301 Seamless Pipe
What is ASTM A312 TP304 pipe?
ASTM A312 TP 304 / 304L stainless steel pipe is the most versatile and most commonly used stainless steel on the market. And these grades are austenitic chromium alloy, also known as “18/8” stainless steel, because the composition of the steel is 18% chromium and 8% nickel.
YUHONG offers ASTM A312 TP304 seamless stainless steel pipe in many years experiences.
ASTM A312 TP304 seamless pipe is used for various applications, which require pipe have high strength and excellent corrosion resistance in harsh environment, TP304 stainless steel is a ideal grade to balance cost and usage, its properties enable to meet the most conditions.
ASTM A312 TP304 Stainless Steel is the most used 300 series stainless steel grade, it combines of sufficient Chrome and Nickel contents to possess excellent properties, ASTM A312 TP 304 has good corrosion resistance, good formability and good weldability to meet various applications.

How to test a SS 304 Seamless Pipe?
The 304 seamless pipe are tested to check their integrity and properties. Below are the most common tests performed on them:
1.Hydrostatic tests to check any leaks in the pipe.
2.Ultrasonic testing determines the wall thickness of a pipe. This helps determine the pressure it can bear.
3.Magnetic particle inspection is a complex test that checks any imperfections by applying iron particles.
4.The Charpy Impact test helps measure the toughness of the material.
5.In the Positive material identification test, x-ray radiation is used to check for the existance of defects in the pipe.
