Stocked Grades

Oil & Gas Steel

Hillfoot has developed significant expertise in the supply of steel grades required for downhole, subsea and wellhead applications in the oil and gas sector.

Our team have an in-depth knowledge of the technical specifications required in the industry, and have set up systems that ensure we deliver steel of the right specification and quality within timescales that match each customer’s production schedules.

Having spent many years partnering and delivering innovative solutions to OEMs related to cost, quality and lead times, alongside developing relationships with steel mills worldwide, we have established a reliable supply chain that can source the steel grades you need in the quantities you require.

Our supply model for these grades has developed to one whereby we stock, supply and service contractual requirements, rather than holding full product lines for general consumption. This allows us to uphold a service which is marketing leading, and ensure the correct availability of product which confirms to the correct level of technical and quality requirements for our contractual clients.

Even though the energy steel grades listed below are the ones we typically supply, if you require a steel grade that is not stocked our established supply chain and friendly, reliable team of steel experts are available and more than willing to source specialist grades for you.

Alongside ensuring your steel is delivered in the exact form suitable for your production process, we are dedicated to giving our clients a high value service. This is demonstrated through our wide range of processing services such as cutting, machining, forging and heat treatment.

Similar Grades

Grades of similar (not identical) chemistry. Please note the similar grades are based on chemistry only, and may not meet the necessary mechanical properties (in the standard ‘as stocked’ state).

Grades for Potential Substitution

Grades capable of achieving similar mechanical properties (material may need further treatment to achieve the desired properties). The potential substitution grades are based on mechanical properties, not necessarily the chemical analysis.
