The high amounts of molybdenum and chromium content in 2205 offer strength, improved pitting and consistent stress corrosion cracking resistance.

Austenitic stainless does not like middling-high heat. It performs well up to 600 °F (315 °C), but higher temperatures in the range of 800-1600 °F.

STAINLESS STEEL 347/347H Better high temperature properties than 304 or 304L. Generally used for parts which are intermittently heated up to 1500°F.

All Stainless Steel pipes are offered with a NACE 3.1 Certification, Mill Test Certification and ISO 17025 Standards by a Government

The offered range of welded pipe is made utilizing high grade raw material and innovative techniques in strict compliance with the quality norms

Company has perfect quality assurance system, advanced testing equipment and high-qualified management team with control over series of activities
