Application:
304 stainless steel flat bar: It is a general-purpose oxidation-resistant steel that can withstand repeated heating below 870°C.
316 stainless steel flat bar: high temperature has excellent creep strength, used as heat exchange parts, high temperature corrosion resistant bolts.
410 stainless steel flat bar: used as parts for oxidation resistance below 800 °C.
420 stainless steel flat bar: high hardness in the quenched state, good corrosion resistance, used as steam turbine blades.
The stainless flat bar can be composed of various stress components according to the different needs of the structure, and can also be used as a connector between components. Stainless steel flat bar is widely used in various building structures and engineering structures.
Typical uses are:
1. Beam
2. Bridge
3. Transmission tower
4. Lifting and transporting machinery
5. Ship
6. Industrial furnace
7. Reaction tower
8. Container rack
9. Warehouse shelves
