B30 copper steel clad plate

B30 Copper Steel Clad Plate - High-Performance Bimetallic Composite Material

When your project demands the corrosion resistance of copper-nickel alloy with the structural strength of steel, our B30 copper steel clad plate delivers exceptional value. Manufactured by Baoji City ShenAo Metal Materials Co., Ltd. through advanced explosive welding technology, this bimetallic composite material achieves a metallurgical bonding strength of ≥140 MPa with a bond rate exceeding 99% verified by Ultrasonic Testing Class I. Our production capabilities accommodate dimensions up to 3000 mm in width and 12000 mm in length, with customizable steel thickness from 10–50 mm and copper cladding from 2–10 mm. You get the anti-biofouling and erosion-corrosion resistance of B30 (70/30 Cupro-Nickel) combined with the load-bearing capacity of high-grade steel.

What Makes Our Bimetallic Composite Material Stand Out?

Our copper-steel composite plates illuminate a basic building challenge. You require hardware that withstands unforgiving seawater situations without the restrictive taken a toll of strong combination construction.

The item highlights a B30 copper-nickel combination layer metallurgically fortified to basic steel substrates like Q345R or A516 Gr.70. This isn't surface plating. It's an atomic-level combination that remains indistinguishable beneath warm cycling and mechanical stress.

The B30 cladding layer gives predominant resistance to high-velocity seawater stream up to 4.5 m/s. It actually shapes a defensive oxide film that anticipates biofouling. In the mean time, the steel base conveys the basic keenness your weight vessels and marine structures require.

You decrease fabric costs by 30-50% compared to strong copper-nickel plates whereas keeping up full erosion security where it things most.

Technical Specifications

Key Advantages for Your Applications

Cost-Effective Engineering

You dispose of the cost of full combination development. Our composite plan employments reasonable basic steel for bulk volume whereas giving copper-nickel assurance as it were where needed.

Exceptional Bond Integrity

The hazardous welding prepare makes shear qualities surpassing 210 MPa. This outperforms ASTM B898 measures. Your plates won't delaminate beneath warm development, mechanical stacking, or weight cycling.

Superior Erosion Performance

The B30 surface stands up to chloride-induced push erosion breaking and setting. It handles erosion-corrosion in high-velocity seawater applications. You do not require extra anti-corrosion coatings or painting.

Customization for Your Requirements

We alter thickness proportions, measurements, and base steel grades to coordinate your particular working conditions and plan life prerequisites.

Frequently Asked Questions

Q: What is the fundamental advantage of B30 over B10 clad plates?

A: B30 (70/30 cupro-nickel) offers essentially higher resistance to erosion-corrosion in high-velocity seawater up to 4.5 m/s compared to B10 (90/10). It gives way better assurance for requesting marine applications.

Q: Can this fabric be welded utilizing standard procedures?

A: No, it requires specialized move welding. You must utilize a steel-side weld taken after by copper-alloy overlay. This avoids press defilement in the cladding weld, which seem cause hot cracking.

Q: What cladding thickness alternatives are available?

A: We offer standard cladding thickness from 2mm to 10mm. The fitting thickness depends on your required erosion remittance and anticipated plan life.

Q: How does the bond interface respond to warm cycling?

A: The metallurgical bond from hazardous welding remains greatly steady. Your plates withstand rehashed warm development and withdrawal without delamination risk.

Q: Does the B30 surface require extra protection?

A: No portray required. The B30 layer actually shapes a defensive oxide film in seawater that gives characteristic erosion resistance and biofouling protection.

Q: What benchmarks does your generation follow?

A: Our product manufacturing follows to ASTM B898, ASME SB-898, and NB/T 47002.4 benchmarks. We guarantee compliance with universal quality necessities.
