Q235B+316L Stainless Steel Composite Plate - Enterprise-Grade Bimetallic Solution

The Q235B+316L stainless steel composite plate from Baoji City ShenAo Metal Materials Co., Ltd. delivers exactly that. Engineered through precision explosion welding technology, this bimetallic plate combines a robust Q235B carbon steel base with a corrosion-resistant 316L stainless steel cladding layer. You get an interface shear strength exceeding 210 MPa and a bonding rate of ≥98%, meeting stringent GB/T 8165 and ASTM A264 standards. With 17 years of manufacturing expertise and customizable dimensions up to 2500mm width and 6000mm length, we help you reduce material costs by 30-50% while maintaining structural integrity.

What Makes This Composite Plate Different?

Conventional strong stainless steel plates can deplete your budget rapidly. Our composite arrangement addresses this challenge head-on.

The base layer employments Q235B carbon steel. It gives the mechanical quality you need—235 MPa abdicate quality and great affect durability. This establishment underpins overwhelming loads without breaking your budget.

The cladding layer highlights 316L stainless steel with 2-3% molybdenum substance. This gives you prevalent resistance to setting and cleft erosion, particularly in chloride-rich environments.

Between these layers lies the mystery: blast welding makes a metallurgical bond that won't delaminate beneath warm cycling or mechanical stretch.

Where You'll Use This Material?

Petrochemical and Refining Operations

Your refining columns and weight vessels taking care of acrid rough require security from H2S-induced push erosion. The 316L surface layer gives precisely that, whereas the Q235B base handles basic loads efficiently.

Desalination and Marine Engineering

Saline situations devastate standard steel rapidly. This composite plate exceeds expectations in evaporator shells for Multi-Stage Streak desalination plants and seaward stage components where saltwater contact is constant.

Fine Chemical and Pharmaceutical Production

Large aging tanks and response pots request both virtue and quality. The 316L insides meets pharmaceutical-grade prerequisites, whereas the carbon steel backing keeps creation costs sensible.

Frequently Asked Questions

Q: How does the composite plate compare to strong 316L stainless steel in cost?

A: You'll regularly spare 30-50% on fabric costs. The Q235B base gives basic bolster at carbon steel estimating, whereas the lean 316L cladding conveys full erosion security where it contacts your prepare media.

Q: Can I weld this composite plate?

A: Completely. Standard welding methods apply. The moo carbon substance in 316L anticipates sensitization amid welding, killing the require for post-weld warm treatment in most applications.

Q: What's the least cladding thickness you can provide?

A: We ordinarily suggest a least 3mm cladding layer for solid erosion security. Be that as it may, we can customize based on your particular destructive environment and anticipated benefit life.

Q: How do you guarantee the holding quality?

A: Every plate undergoes ultrasonic testing to verify the ≥98% bonding rate. We also perform shear strength testing on sample pieces from each production batch to confirm the interface exceeds 210 MPa.

Q: What's the typical lead time for custom orders?

A: Standard specifications ship within 2-3 weeks. Custom dimensions may require 4-6 weeks depending on your exact requirements and order volume.
