Overview
UNS S32750 is a stainless steel containing high chromium, high molybdenum, high nitrogen and low carbon for excellent corrosion resistance and high strength. It excels in highly chlorinated and acidic environments and is widely used in the chemical, oil and gas industries.
Heat treatment is the process of changing the organizational structure and properties of UNS S32750 through process treatments such as heating and cooling. Carbon is an important alloying element in UNS S32750 and has a great influence on the properties of UNS S32750.

Some of the quality tests carried out by us includes:
| Corrosion Test | Conducted only when specially requested by the client |
| Chemical Analysis | Test done as per required quality standards |
| Destructive / Mechanical Testing | Tensile | Hardness | Flattening | Flare | Flange |
| Reverse-bend and Re. flat tests | Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end |
| Eddy Current Testing | Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System |
| Hydrostatic Testing | 100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s . |
| Air Under Pressure Test | To check any evidence of air leakage. |
| Visual Inspection | After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections |
Supplementary Testing
Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing.
