HOT ROLL BONDED CLAD PLATES
Hot Rolled Clad Plates are metallurgically bonded composite of two layers produced through roll bonding which is done by hot rolling a welded composite assembly of steel clad plates.
- The bond is created by high temperature and high pressure during hot rolling
- A typical combination is a thin corrosion-resistant alloy (CRA) as clad material and a thick carbon steel as base material
Clad stainless steel plate is used in a variety of industrial fields like Oil & Gas production & refining construction, and chemical, Pharmaceutical, and Flue gas desulphurization industry for various equipments.
HOT ROLL BONDING PROCESS
Our production equipment is highly automated and provides precise tolerances concerning dimensions, flatness and surface quality & properties
CORROSION RESISTANT ALLOYS FOR UNPARALLELD STAINLESS SECURITY
| Thickness (mm) | Width (mm) | Length (mm) |
|---|---|---|
| 8.0 - 20.0 | 1000 -1200 | Up to 8000 |
Minimum thickness of cladding alloy is 2.0 mm.
Tolerances as per ASTM A264, A265

TESTING & INSPECTION
MULTIPLE CHECKS FOR ULTRA DURABILITY
Testing and inspection of Clad Plates are performed in accordance with the specification of ASTM A264 and A265.
> Tensile Test:
The tensile properties shall be determined by a tension test of the composite
plate or base plate for evaluation of strength of material.
> Bend Test:
Bend tests with the cladding metal outside indicate the strength of the bond.
> Shear Strength:
The ASTM specification requires minimum shear strength of 140 MPa.
> Ultrasonic Test:
Ultrasonic inspection is performed as per ASTM A264/A265
> Corrosion Test:
ASTM A262 Practice E for Stainless steel cladding material
ASTM G48 method A for nickel alloy
