Carbon Steel

Product Details:

Carbon steel is an alloy consisting of iron and carbon. Several other elements are allowed in carbon steel, with low maximum percentages. These elements are manganese, with a 1.65% maximum, silicon, with a 0.60% maximum, and copper, with a 0.60% maximum. Other elements may be present in quantities too small to affect its properties.

 

There are four types of carbon steel based on the amount of carbon present in the alloy. Lower carbon steels are softer and more easily formed, and steels with a higher carbon content are harder and stronger, but less ductile, and they become more difficult to machine and weld. Below are the properties of the grades of carbon steel we supply:

• Low Carbon Steel – Composition of 0.05%-0.25% carbon and up to 0.4% manganese. Also known as mild steel, it is a low-cost material that is easy to shape. While not as hard as higher-carbon steels, carburizing can increase its surface hardness.
• Medium Carbon Steel – Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong, with long-wearing properties.
• High Carbon Steel – Composition of 0.55%-0.95% carbon, with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.
• Very High Carbon Steel - Composition of 0.96%-2.1% carbon. Its high carbon content makes it an extremely strong material. Due to its brittleness, this grade requires special handling.

Product Details:

S355JR+AR Durbar® S355JR+AR is a strong, robust floor plate offering a range of benefits including scope to reduce construction costs Floor plate with structural integrity Durbar® S355JR+AR is part of Tata Steel’s range of hot-rolled structural steel floor plate. Extensively tested and proven, Durbar’s structural properties reduce construction costs by eliminating the need for separate structural and flooring components. Versatile and durable, Durbar is manufactured with a distinctive raised stud pattern for slip resistance. We have been producing Durbar to the highest quality standards for more than 40 years. Durbar is certified to ISO TS 16949:2009 and meets the requirements of the Construction Products Directive. Tested for slip resistance Durbar has been tested and assessed for slip potential. Its pattern of studs creates a slip-resistant surface at all angles and allows plates to be used in any direction. Wessex Test Equipment Limited, an independent research establishment, tested Durbar both wet (clean water) and dry in accordance with the standard and guidelines shown below and assessed its potential for slip as extremely low for the dry samples and low for the wet samples1 . Testing was conducted on uncoated Durbar under laboratory conditions. The actual slip-resistance of Durbar will depend upon the real-life application and the environment in which it is used. Galvanising, painting or coating Durbar can influence its slip resistance. Plate ID Sample reference Pendulum test value (WET) Durbar floor plate H 306 21 010 1, 2, 3, 4 47, 47, 47, 47 H 306 20 010 1, 2, 3, 4 42, 46, 42, 48 UK Slip Resistance Group Guidelines (issue 4, 2011) The potential for slip value reported applies in the instance of access by able-bodied pedestrians.

• High slip potential 0-24
• Medium slip potential 25-35
• Low slip potential 36-64
• Extremely low slip potential 65+

The results show that under water wet conditions or other similar contaminants the majority of those floor areas tested exhibit a low potential for slip. 1 BS 7976-2:2002 Pendulum Testers scope for use in the determination of slip/skid resistance of surfaces Mechanical properties Min. yield strength ReL (N/mm2 ) Min.-max tensile strength Rm (N/mm2 ) Min. elongation after fracture A (%) Impact test L0 = 5.65√S0 3 ≤ t ≤ 12.5 Temp ºC Min energy J S355JR+AR 355 470-630 20 20 27 Notes: 1.

STRUCTURAL STEELS in accordance with SANS 50025 / EN 10025 – 2004

GENERAL DESCRIPTION These grades of steel are intended for structural work where no significant forming or bending must be done. These grades can be bolted, riveted and welded in a full range of structural and fabricated items including bridges, box girders, cranes and other general structural projects. The grade designations of SANS 50025 / EN10025-2 refer to the minimum yield strength of each grade for thicknesses less than or equal to 16mm. The steel should be selected in accordance with the strength requirements as shown in Table 2.The JR, J0 & J2 suffixes refer to different impact requirements. An average impact energy value of 27 Joules must be achieved on full size specimens in the longitudinal direction in all applicable cases. The suffix AR refers to the As-Rolled condition. If the material is normalised then this will be indicated by a '+N' appearing as a suffix. The SANS 50025 / EN10025 structural steel grades are all readily weldable by means of the usual metal arc processes.
