Our Offering

Special Melted Products is a leading supplier of high-quality specialty steels and nickel-based superalloys for the Aerospace, Oil & Gas and Civil Nuclear markets. Our specialty alloys are designed for superior performance in mission-critical applications.

Thanks to our consistently outstanding quality and reliability, we have become a trusted partner for leading OEMs, forgers and machine shops across multiple geographies and end markets. For our customers we are a “one-stop shop” for multiple melted alloys and components.

Aerospace

SMP is a leading producer of remelted low-alloy, stainless and maraging steels for critical jet engine and air frame applications.

SMP has core expertise in the production of critical rotating mainline engine shafts for the world’s leading jet engine OEMs. The combination of our melting, forging, heat treatment and machining capabilities make us a one stop shop for this product. SMP is also a leading supplier of reforging quality billet and machining bar for other component producers within the aerospace supply chain.

SMP supports the major oilfield service companies with its proprietary high strength stainless steel non-magnetic grades used extensively in bottom hole assemblies (BHA).

SMP’s material is preferred due to its machinability and high performance within the field. SMP has the full manufacturing capability to produce these grades through remelting, forging and machining including the production of API drill collars.

Via an established global distribution and machining network SMP also supplies Nickel-based superalloys for the use in critical drilling, well completion and well head equipment. SMP’s considerable manufacturing capability enables it to produce these alloys in a large size range and heat treatment conditions, particularly making us a world-leading producer of oil & gas 718 grades.

Oil & Gas

Nuclear

SMP is a leading supplier to the UK’s civil nuclear industry offering not only material supply but project management services.

SMP is a very long-standing supplier and have all the stringent quality documentation and procedures in place to meet the demanding requirement of this industry. SMP is actively engaging in research with regards to the new generation of SMR reactors.

Our goal is to be the supplier of choice for the industries we serve bringing premium products and innovative solutions to our customers
