High Yield Steel
From heavy transporters , to steel structures and mobile cranes, our high yield steels are designed to work under incredible load stresses. Steels of this type are also supplied as special offshore grades to the offshore industry.
Our structural grade material provides maximum strength (a minimum tensile strength of up to 1300 MPa), with good welding and bending properties.
High tensile steel is an ever evolving technology with increasing demands for higher yield and lower weights. The crane and lifting industry is one such market which is driving this technology forward and as a result, some of our steels have only become available on the market in the last couple of years.
High yield steel is an extremely cost effective solution – for example, it will completely resolve the issues as a result of ‘over-engineered’ design projects as it will reduce the volume of steel material required without compromising quality or indeed, safety. Certainly, in the case of steel framed buildings, such a cost reduction and simplification of design is a welcome feature.
The material can be supplied as heavy plates, fabricated sections or sheets. Masteel UK Limited can supply high yield steel from stock on a global basis. Care should be taken to check the suitability when choosing high yield structural steel.
S700MC
S700MC – a high yield structural steel supplied under the EN10149: Part2 specification. Due to the materials high yield (700Mpa min.) it can be used in a variety of load bearing applications.
Popularly, the steel is used for cold formed components including cold pressed parts and sections. Typical applications include steel frames, load bearing beams and pipework.
S700MC offers excellent bending and folding properties though case should be taken in ensuring that the steel is the right specification for the job.

S1100QL & S1300QL
S1100QL (& S1300QL) are relatively new steels on the market that can conceivably be classed as “Ultra High Yield Structural Steels” boasting a minimum tensile strength of 1100 MPa and 1300 MPa respectively.
Lighter & Stronger Steel
These new steels have only hit the market recently but are already being used and specified in the heavy lifting industry. This industry has an ongoing requirement for stronger and lighter structural sections which are used in the manufacture of crane booms. Both S1100QL & S1300QL are a perfect fit for this purpose.
The material is quenched and tempered and is relatively easy to bend and weld but its the strength and wear resistance which makes this steel a highly sort after and marketable item.
Technical specifications are available on request form our Sales Office.
S960QL
Grade 960QL is a high strength structural steel in the quenched and tempered condition which gives the material excellent strength and abrasion resistance.
S890QL is a water quenched & tempered steel which complies with the EN10025:6:2004 specification.
