Ganpat Metal supplies SA 178 Grade A tubes for industrial boiler and heat-transfer applications. Manufactured from carbon steel, these tubes are specified by buyers who need defined chemical composition, tensile strength, yield strength and elongation characteristics for boiler equipment. We serve industrial procurement teams, equipment manufacturers and maintenance buyers sourcing boiler tubes for fabrication and replacement requirements.
Contact Ganpat Metal for SA 178 Grade A tube availability, dimensional options, technical documentation and quotations for domestic and export orders.
GM SA 178 Grade A boiler tubes are intended for applications requiring carbon steel tubing that meets the applicable ASTM A178/A178M or ASME SA-178 specification. Grade A has a minimum tensile strength of 325 MPa, minimum yield strength of 180 MPa and minimum elongation of 35%, based on the supplied reference data.
For industrial buyers, selecting the correct grade is essential because SA 178 grades differ in chemical composition and mechanical properties. Ganpat Metal supports enquiries for Grade A tubing based on the technical specification, dimensions and quantity required for the application.
