Materials

NiRo Works up all common shared stainless steel pieces up to high-alloy materials and nickel-based materials in accordance to reviewed approvals. The high quality products are preferred application in the process technology, environmental-, paper-, chemical- and power plant industry.

Stainless steel

1.4301 / 1.4307 / 1.4541

Water and easily polluted sewages, food and organic acids, up to ph-value 4,5 resistance in chlorides poor fluids.

1.4404 / 1.4571

Higher common resistance than in above group, preferred for environmental-, paper- and chemical industry, even by higher chlorides content.

1.4432 / 1.4435 / 1.4436

Higher resistance than above group against oxidizing acids and chlorides containing fluids.

1.4439

Higher resistance than above group against oxidizing acids and containing chlorides fluids e.g. seawater and hypochloridbase.

Special stainless steel

1.4529 / 1.4547 / 1.4562 / 1.4565

highest resistance in acids, chlorides fluids, e.g. seawater, high sulphuric acid resistance.
