Our quality assurance system is certified in accordance with the ISO 9001 standards. An independent quality assurance department is responsible for all working procedures required to ensure that all manufacturing processes are carried out in accordance with international technical delivery conditions like ASTM/ASME, EN, API and with the customer specifications.

These stainless steel have the good heat-resisting performance, is suitable in the steam environment or 550℃ and the above temperature.

310S Stainless steel is a combination of good strength and corrosion resistance in temperature up to 2100oF (1149℃). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.


309S High corrosion-resistant, chromium nickel grade with carbon limited to .08 to reduce carbon precipitation during welding. Maximum Recommended Service Temperature Continuous 1100℃ /Intermittent 980℃


304H the carbon content is controlled to a range of 0.04-0.08 to provide improved high temperature strength to parts exposed to temperatures above 800°F (427℃)


321H advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427℃ to 816°C).


347H in higher elevated temperature allowable stresses for these stabilized alloys for ASME Boiler and Pressure Vessel Code applications. The 321 and 347 alloys have maximum use temperatures of 1500°F (816°C)
