Maria Pipes and Tubes, located in Kuala Lumpur, Malaysia, has built a solid reputation as a manufacturer and supplier of top-notch stainless steel tubing. Their Stainless Steel 304H Instrumentation Tubing is specifically designed to handle the rigors of high-temperature and precision applications, boasting impressive strength and resistance to corrosion. Offered in seamless form and crafted to meet respected standards like ASTM A269, this tubing is a go-to choice in critical industries such as petrochemical, dairy, and food processing. The company is committed to upholding international quality standards, ensuring that their tubing can withstand even the toughest operational conditions.
The Stainless Steel 304H Instrumentation Tubing is made from a high-carbon austenitic alloy, containing about 18–20% chromium, 8–10.5% nickel, and a higher carbon content of 0.04% to 0.10%. This unique composition enhances its strength at elevated temperatures and improves its creep resistance. With mechanical properties that include a minimum tensile strength of 515 MPa, yield strength of 205 MPa, and an elongation of at least 40%, it can also reach a maximum hardness of HRB 92 or HB 201—ensuring it maintains structural integrity under both thermal and mechanical stress.
