Layla Sheets and Plates, located in Cairo, Egypt, stands out as a top manufacturer and supplier of NACE MR 0103/0175 HIC Boiler Sheets and Plates. This company has built a solid reputation for crafting high-performance steel products that are specifically designed to withstand hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSC) in tough environments. Their NACE-compliant Boiler Sheets and Plates are meticulously engineered to meet the rigorous demands of the oil, gas, and petrochemical sectors. Layla Sheets and Plates prides itself on delivering exceptional quality, precise manufacturing, and dependable delivery, providing materials that ensure safety and durability even in corrosive service conditions.
The NACE MR 0103/0175 HIC Boiler Sheets and Plates are made from carbon steel, enhanced with controlled amounts of manganese, sulfur, and trace alloying elements. This steel undergoes special processing and testing to effectively resist hydrogen-induced and stress corrosion cracking in sour service environments. These plates boast a tensile strength ranging from 485 to 620 MPa, a yield strength of about 250 to 450 MPa, and impressive impact toughness. They are subjected to rigorous metallurgical control and ultrasonic testing to guarantee outstanding resistance to HIC and SSC damage.
Grade : ASME SA 516 GR.70N 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 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.
