VINAY METALS is able to supply fine-grain pressure vessel quality HIC-tested steel plates according to the Petrobras specification N–1706.

MASTERHIC which is VINAY METAL’s own designation for HIC-resistant steel is supplied according to ASTM /ASME A / SA 516 Grade 60, 65 & 70. Manufactured with desulphurization, dephosphorization, lade refining, and vacuum degassing, the material is an ultra-clean and homogenous steel that is particularly suited for pressure equipment in sour gas applications.

Features:

• Petrobras N-1706 Class A & B compliant
• Fully tested for susceptibility to hydrogen-induced cracking (HIC)
• Meets specifications applied by the Oil, Gas & pressure vessel industry
• Supplied according to NACE MR0175 and MR0103
• Low carbon equivalent with excellent weldability

The comprehensive stock range available Our SA 516 Gr 60 HIC and SA 516 Gr 70 HIC is two or the more popular HIC tested grades used in wet/sour gas environments.

These SA 516 HIC-tested steels are vacuum degassed with extra low sulfur, phosphorus, and residual elements for maximum resistance to sulfide stress corrosion, HIC, and notch toughness sensitivity.

These plates are used in the pressure vessel industry and primarily in refineries, chemical plants, and power plants.

Vacuum degassed with low sulfur and residual elements

British Standard European Norm ASTM/ASME DIN
BS1501-161-430A EN10028 P265GH A/SA516 – Grade 60 DIN 17155 HII

SPECIFICATION

• Grade ASME SA 516 GR.60N Boiler and Pressure Vessel Steel Plates
• Width 1000mm-4500mm
• Thickness 5mm-150mm
• Length 3000mm-18000mm

Supply Condition As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.

Impact tested 52° C

Tempering Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between the purchaser and supplier then the steel is also to be tempered at 1200 F.

Applications Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.

Process of Manufacturing Hot-Rolled (HR) Testing-
The test requirements or needs can be easily fulfilled through a test like chemical composition analysis, material grain size determination, line discontinuities, freedom from defects, tolerance and dimensions, bend test, tensile test, Charpy impact test, and ultrasonic test. Some other test includes the Destructive test or nondestructive test, Mechanical test, tensile test, hardness test, micro & macro test, positive material test, intergranular corrosion test, flattening test, and flaring test.
