STAINLESS STEEL

Austenitic steels contain some nickel elements, making the steel resistant to various types of acids at different concentrations and temperatures. Duplex stainless steel has two kinds of metallographic structure of Austenite and Ferritic stainless steel, characterized by relatively good strength properties at elevated temperatures and good weldability.

The most commonly used stainless steel of LKALLOY supplying is AISI 316Ti, AISI 347, 2205 and 2507 steel in several forms and specifications, such as pipe, tubing, bars, and pipe flanges. These materials are widely used in oil and gas industrial, marine industrial, chemical processing and nuclear industrial due to their excellent strength and pipe, tube, plate and pipe fittings in the solution treated and quenched condition.

Area of applications

Stainless Steel is used in shipbuilding, chemical, dyeing, brewing, off-shore, pharmaceutical, textile, petrochemical, plastics and paper industries.

Chemical processing| Bolts, nuts working in contact with salts, parts and components of ships and ships, medical implants, surgical implants, springs, Petrochemical engineering| Oil and gas pipeline, heat exchanger, fittings and installations.

Construction| Balustrades, frames, ornaments, welded fittings, installations, parts of machines producing rubber.
