Quenched and Tempered Steel Plates

Product Details:

Quenched and tempered plate, a steel that is stronger and harder than ordinary carbon steel. The product is used for the manufacture and repair of machinery and structures where greater abrasion resistance or higher yield strength are required.

It is not uncommon in our industry to find the same type of steel plate given different names by different engineers.

Plates of this type are variously described as:

• High Strength Quenched and Tempered Steel Plate
• High Yield Quenched and Tempered Steel Plate
• High Strength Structural Steel Plate,
• High Yield Structural Steel Plate
• High Strength Low Alloy Steel Plate
• HSLA

This type of steel plate is used in the manufacture of cranes, forklifts, bridges, offshore fabrications, mining and quarrying equipment, mooring equipment, and vehicle chassis to name but a few applications.

Machining:

• The RQT range can be machined and drilled using high-speed steel or cemented carbide tools.  The approximate hardness of the RQT range can be obtained from the value of the ultimate tensile strength and falls within the range 240-280 BHN.

Welding:

• Care should be taken to avoidhydrogen cracking and there are many factors to take into consideration before welding.  Full technical guidance for welding is available from the sales/technical team at Triton alloys Co.

Technical Specifications:

Flame Cutting:

• RQT steels can be cut satisfactorily using conventional oxy-fuel gas practices, in many cases without the need for preheat, as long as cutting procedures take into account plate thicknesses and carbon equivalent values. Water jet, where no heat is generated, or plasma cutting can also be used. Care should be taken when cutting under water as the quenching effect could result in a high hardness edge forming.  With all thermal cutting processes care should be taken that cut edges are free from sharp notches.

Cold Bending:

• Quenched & Tempered steels can be readily cold formed however the power required will be higher (70%) than that for mild steel of the same thickness.  It is recommended that the largest possible bending radius should be used, and generally the inside radius should not be less that 3 times the plate thickness.

Typical Application of Domex 700 Plate
The extra high strength steel grades are used in applications such as truck chassis, cranes and earthmoving machines. In these applications, the high strength of the steels is used to save weight and/or to increase the payload. As a result of this and the good formability of the steels, the total costs can be reduced.
The additional high quality steel evaluations are utilized as a part of uses, for example, truck body, cranes and earth moving machines. In these applications, the high quality of the steels is utilized to spare weight and/or to build the payload. As a consequence of this and the great formability of the steels, the aggregate expenses can be diminished. Normal applications are vehicle chassis, holder casing structures, steel extensions and building developments, chimney stack cases, rail wagons, snow sheds, various types of poles i.e. applications where a consumption safe steel is required together with high quality.

Product Details:

The mechanical properties introduced to the steel through this processing route are virtually equivalent to those obtained by heat treating conventionally rolled or forged steel. TMCP involves controlled hot working and microalloyed steel compositions.When TMCP is chosen as the process route, the rough steel section (i.e. the slab) is heated to a temperature regularly used for hot working operations (about 1200°C). The initial hot working (‘roughing’) is carried out in a normal fashion, but the final hot work reduction or ‘finishing pass’ is carried out at a lower temperature than would be used for older processes.

100 ksi/690 MPa steel plate is a high strength, steel plate produced using a Thermo Mechanically Controlled Process (TMCP). This process allows the plate to have a superior surface quality, excellent weldability, better forming and higher charpy values than Q & T plate.100KSI steel plate was developed for applications that require a high strength-to-weight ratio.  It has many of the same properties as A514 carbon steel plate, including high strength, machinability and weldability.  It is available as temper-leveled plate and sold under a variety of tradenames.  The most common tradename is Domex 100XF. 100KSI / 100XF has a 100,000 psi minimum yield and tensile strength.
