Austenitic Stainless Steel

We deal with Chrome - Nickel (300 Series) and Chrome - Manganese (200 Series). Typical applications for Chrome - Nickel include food processing, chemical plants, pharmaceutical equipment, hospitals, textile, architectural, building construction, kitchenware, consumer durables etc. Its applications include kitchenware, cutlery, sinks, automotive trim, architectural, buildings, furniture, buses, trains and ornamental tubes.

Excellent resistance to atmospheric corrosion
Effectively withstand attack of organic acids and fair resistance to mineral acids
Good high temperature properties
Excellent low temperature ductility and impact strength
Duplex Stainless Steel

Duplex Stainless Steel grades contain relatively high Chromium (between 18% and 28%) and moderate amounts of nickel (1% to 8%). This combination of ferritic and austenitic structures is called duplex. These grades exhibit high resistance to stress, corrosion cracking and chloride ion attack and have higher yield strength than that of austenitic or ferritic steel grades. These grades are used in marine applications, offshore platforms, paper and pulp industry, chemical, petrochemical and desalination plants.

Features
Material saving
Possible to do high quality fabrication and welding
Martensitic Stainless Steel

These are plain chromium grades containing 11.5 % to 18% of chromium with relatively high carbon content (0.1% - 1.2%). Initially developed for cutlery, these are well suited for applications requiring high hardness and resistance to abrasion and erosion. Martensitic Stainless Steel grades are commonly used for knife blades, turbine blades, surgical instruments, fasteners, shafts, spindles, valves and pins.

Features
Magnetic
Fair cold forming characteristics
Can be hardened by air-cooling
Can be welded
Best corrosion resistance
Ferritic Stainless Steel

These are non-hardenable plain chromium grades with chromium content varying from 10.5% to 28% and with low carbon content. The ferritics can be polished or buffed to achieve high luster. These grades are employed in applications where the desired formability, weldability and corrosion resistance is between those of martensitic and austenitic types.
