Stainless Steel Grades | Stainless Steel Price | grades of steel - Ambica Steels manufactures multiple grades of steel in India

duplex stainless steel

Ambica's steels are melted, cast and formed with the perfection and care.

Every part is continually and stringently checked for quality and certified.

These facilities are supported by precise input data and work schedules tailored to the individual customer’s specifications, and by continuous ongoing quality checks of all features relevant to the particular order.

Ambica Steels is the largest producer of Duplex Stainless Steel Long Products in India. Ambica Steels produces these materials for a wide variety of applications and industrial sectors, e. g. Pulp and paper industry, Desalination plants, Flue-gas cleaning, Cargo tanks and pipe systems in chemical tankers, Seawater systems, Firewalls and blast walls on the offshore platforms, Bridges, Components for structural design, Pressure vessels, Heat exchangers, Water heaters etc.

These user segments are the benchmark for quality. Ambica Steels offers various materials in the Duplex 1.4462 grade like Concast Billets, Hot Rolled & Bright Bars, and Forging Ingots. Ambica Steels is currently exporting these materials to various countries worldwide and the demand is increasing. Our round bars in Duplex 1.4462 grade meet optimum PREN values and qualify for the Notch values of 50 - 60 Joules, in sub zero temperatures of up to 100 Degrees. Round sizes available are 16 mm up to 100 mm diameter in lengths up to 7.5 meters.

Due to its two-phase microstructure, Duplex steels are extremely tough to produce. It took us more than several years of constant trials & errors at Ambica Steels, before gaining a complete control over this steel. The dual phase structure demands a perfect balance in the chemistry of these steels. Duplex steels also show an irregular behaviour when undergoing various hot working processes. But thanks to the strong determination of our Research & Development team, as Ambica Steels now enjoys the reputation of being one of the most reliable supplier of Duplex materials in domestic as well as the international market.

Ambica Steels specializes into the production of 17/4ph Stainless Steel (also known as DIN 1.4542 and AISI 630), which is a martensitic precipitation/age-hardenin stainless steel offering both high strength & hardness (up to 572°F / 300°C) along with an excellent corrosion resistance.

This alloy is martensitic in structure in the annealed condition and is further strengthened by a low temperature heat treatment, which precipitates a copper-containing phase in the alloy and very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

Ambica Steels offers this material in following heat treatments:
Condition Temperature °F Time, h Quench
H900 900 4 Air Cool
H1025 1025 4 Air Cool
H1075 1075 4 Air Cool
H1150 1150 4 Air Cool
H1150M 1400 for 2h, air cool plus 1150 for 4 h, air cool
H1150D 1150 for 4 h, air cool plus 1150 for 4 h, air cool
