The differences between Steel Plates

MS250

A medium strength structural steel plate product with nominal yield strength of 250 MPa.

Guaranteed minimum strength levels

Excellent weldability

Excellent formability

Produced to: AS/NZS 3678

Common Uses of this product

General fabrication, structural members, high rise buildings, bridges, storage tanks.

Warnings

This material should be used in conjunction with the appropriate structural design and welding standards.

An untrimmed (Mill) edge may contain minor surface discontinuities as a result of the rolling process (refer Clause 7 AS/NZS 3678). It is recommended that a minimum of 50 mm be removed from each untrimmed edge.

Where impact testing is required refer to AS/NZS 3678 - 250L15.

MS350

A high strength structural steel product with nominal yield strength of 350 MPa.

Guaranteed minimum strength levels

Excellent weldability

Excellent formability

Produced to: AS/NZS 3678

Common Uses of this product

General fabrication, structural members, high rise buildings, bridges, storage tanks

Warnings

This material should be used in conjunction with the appropriate structural design and welding standards.

Maximum recommended temperature for hot forming 620°C. If heated above 620°C, mechanical properties may deteriorate.

Where impact testing is required refer to AS/NZS 3678 - 350L15.

Bisplate 80

BISPLATE 80 – a low alloy, high strength steel plate with a yield strength three times that of carbon steel and featuring low carbon, excellent notch toughness and good weldability and formability. Utilising the high strength properties of BISPLATE 80
allows reduction in section thickness without loss of structural integrity.

All grades of Bisplate can be readily welded using any of the conventional low hydrogen welding processes. Their low carbon content and carefully balanced, but relatively small additions of alloying elements (Mn, Cr, Mo, Ni, B) ensures good weldability, in addition to the advantages of high strength, impact toughness and high hardness.

Bisplate 320

BISPLATE 320 is a through hardened, abrasion resistant steel plate, offering long life expectancy in high impact abrasion applications.

Applications

BISPLATE 320 offers the optimum combination of hardness, impact and formability for wear applications which require extensive forming/drilling or fabrication, in impact abrasive applications such as:

• Deflector plates
• Chutes
• Storage bins
• Dump Truck liners
• Earthmoving buckets

Fabrication

BISPLATE 320 is a high hardness, abrasion resistant steel with a controlled carbon equivalent for optimum weldability. With appropriate attention to heat input, preheat and consumable selection, BISPLATE 320 can be readily welded to itself and other steels, using conventional processes.

Cold forming of BISPLATE 320 plates is possible in all thicknesses, provided the high strength of this steel is taken into account. Adequate allowance must be made for increased springback relative to mild steel. Heating above 400˚C should be avoided, otherwise the mechanical properties may be affected.
