Product Overview

15CrMo alloy steel coil is a low-alloy chromium-molybdenum heat-resistant steel, widely used for high-temperature pressure-bearing equipment. It is manufactured following GB/T 11251 standard. We supply both hot rolled (2.0–16.0mm) and cold rolled precision coil (0.3–3.0mm). Custom processing services including slitting, cutting, bending, beveling, normalizing & tempering are supported. The material is mainly applied for boiler headers, steam pipeline, heat exchanger components, petrochemical pressure vessels. Export shipment can be supplied with EN10204 MTC for full material traceability.
