General Product Description

ST100XF steel plate is a low-carbon, thermo-mechanical controlled-rolled material with a guaranteed toughness that has been developed for applications where increased strength-to-weight ratios are required. ST100XF is available as temper-leveled, cut-to-length plate and meets or exceeds the requirements of ASTM A656 Grade 100.

Applications

ST100XF plate is designed to be used for transport trailers, construction equipment, crane booms, mobile manlifts, agriculture equipment, rail cars, heavy vehicle frames and chassis.

Mechanical Properties

Tensile testing is performed using plate-type tensile specimens in the transverse direction according to ASTM A6 requirements. The minimum requirements are tabulated below:

NOTE: Inquire for other test specimen orientation, minimum energy requirements, and/or test temperatures.

1) Additional elongation requirement adjustments are allowed per the Tension Test section of ASTM A6.

2) Longitudinal specimen orientation. For sub-size CVN specimens, the minimum average energy is reduced proportionally in accordance with ASTM A673.

Tolerances

Thickness, width, and length tolerances for ST100XF steel plate are in accordance with the requirements of ASTM A6. The flatness tolerance for as-supplied plate is ASTM A6 half-standard flatness. Procedures and tolerances for all other testing shall be in accordance with ASTM A6.

Formability properties

ST100XF exhibits cold forming characteristics similar to those of ASTM A656 Grade 80 and Grade 100. The minimum recommended punch radius, R, and the die width opening, W, as a function of bending orientation for cold bending are provided in the following table:

Weldability

ST100XF steel plate is weldable by conventional electric arc welding processes, using low-hydrogen consumables. Although ST100XF has a chemical composition that is readily weldable without preheating or post-weld heat treatment, a precautionary preheat of 120° C (250° F) is recommended to remove any moisture. When matching consumables are not required, lower strength electrodes are recommended.
