SS 347 stainless steel pipe offers better high-temperature resistance and intergranular corrosion resistance than SS 304, making it ideal for heat-intensive and welded applications.

ASTM A312 TP316L is widely used for subsea and onshore liquid ammonia transportation pipelines due to its excellent corrosion resistance and weldability in harsh environments.

1.4845 stainless steel is equivalent to AISI 310S, a high-temperature austenitic stainless steel.

EN 1.4539 stainless steel is equivalent to ASTM 904L (UNS N08904), a high-alloy austenitic stainless steel known for exceptional corrosion resistance in harsh chemical and marine environments.

EN 1.4550 stainless steel is equivalent to AISI 347, also known as X6CrNiNb18-10, a niobium-stabilized austenitic stainless steel with excellent resistance to intergranular corrosion.

409 stainless steel pipe offers better heat resistance and cost-efficiency for automotive exhaust systems, while 304 provides superior corrosion resistance but at a higher price—choose 409 for standard use, 304 for high-corrosion environments.
