Application
| Demand Industry | The Main Purpose | Steel Grade | Require |
|---|---|---|---|
| - Pre-insulated tube |
TP316/316L, 904L, S31803,S32750, etc |
Use environment: high temperature and high pressure and high corrosion environment (through sulfur, chlorine, chemical substances, etc.) Dual-phase steel series suitable for deep-sea extreme low temperature, high salinity and other harsh environments, Demand for high nickel (904L) series expands |
|
| - Petrochemical |
TP316/316L, 904L, S31803,S32750, etc |
It is used for deep-sea subsea oil well control cables, etc., the demand is relatively small, but the added value is higher than that of general products The direction of development is to work closely with Coil processing enterprises or equipment companies to improve research and development capabilities |
