Technical Specifications of Ka36 Shipbuilding Steel Plate

KA36 Shipbuilding Steel Plate - High-Strength Marine Grade Steel for Hull Construction

KA36 shipbuilding steel plate represents a premium-grade structural steel specifically engineered for marine vessel construction, delivering exceptional mechanical strength and superior corrosion resistance in harsh saltwater environments. This high-tensile steel finds extensive application in hull plating, deck structures, and critical load-bearing components of commercial ships, offshore platforms, and naval vessels. Manufactured to stringent international maritime standards, KA36 steel serves shipyards, marine engineering firms, and offshore construction companies requiring reliable material performance under extreme operational conditions.

What is KA36 Shipbuilding Steel Plate?

KA36 shipbuilding steel plate is a normalized rolled steel product conforming to Chinese GB/T 712-2011 standard for structural steels used in hull construction. The designation "KA36" indicates a minimum yield strength of 355 MPa with Grade A impact toughness properties at ambient temperature. This marine-grade steel exhibits optimal weldability characteristics, allowing fabricators to construct complex hull assemblies through various welding processes including SMAW, GMAW, and SAW methods without preheating requirements in most applications.

KA36 Shipbuilding Steel Plate Technical Specifications

KA36 steel demonstrates a tensile strength range of 490-630 MPa with minimum yield strength of 355 MPa for thicknesses up to 50mm per GB/T 712-2011 Section 5.2. The chemical composition limits carbon content to 0.18% maximum, manganese between 0.90-1.60%, and includes silicon at 0.50% maximum, ensuring balanced mechanical properties and excellent welding performance. Impact energy requirements specify minimum 27J at 0°C for longitudinal test specimens according to Charpy V-notch testing methodology defined in GB/T 229.

Why Choose Our KA36 Shipbuilding Steel Plate

Our KA36 steel plates are manufactured in ISO 9001:2015 certified rolling mills utilizing advanced thermomechanical controlled processing (TMCP) technology, guaranteeing consistent through-thickness properties and minimal dimensional tolerances of ±0.3mm for plates under 20mm thickness. Each production lot undergoes comprehensive third-party inspection by classification societies including CCS, ABS, Lloyd's Register, and DNV-GL, with full mill test certificates (MTC 3.2 per EN 10204) provided documenting chemical analysis, mechanical testing results, and ultrasonic examination records per GB/T 2970 standards.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard minimum order quantity for KA36 shipbuilding steel plate is 5 metric tons per specification, though we accommodate smaller quantities for established clients with ongoing projects. Mixed-thickness orders are accepted provided total tonnage meets the 5MT threshold, enabling shipyards to consolidate procurement across multiple vessel components while maintaining cost-effective mill-direct pricing structures.

Do you provide material test certificates?

Yes, every KA36 steel plate shipment includes original mill test certificates (MTC 3.2) documenting heat number traceability, complete chemical composition analysis per GB/T 4336, mechanical property test results including tensile, yield, elongation and impact values, plus ultrasonic testing reports confirming internal soundness per GB/T 2970 Class I or II requirements as specified by classification society rules.

What is the typical delivery time?

Standard KA36 plate thicknesses from 6mm to 40mm in widths up to 2500mm are typically available from our warehouse stock with 7-10 working days delivery time to major Chinese ports. Custom rolling orders for non-standard dimensions, extra-wide plates exceeding 3000mm, or thickness above 50mm require 25-35 days production lead time from purchase order confirmation, subject to mill scheduling and classification society survey arrangements.

Can you cut to custom sizes?

Our processing facility offers precision plasma and flame cutting services for KA36 plates, accommodating complex hull panel geometries, bracket shapes, and nesting layouts with cutting tolerance of ±2mm on linear dimensions. We provide CNC-controlled beveling for weld preparation at angles from 30° to 45°, plus additional services including shot blasting to Sa 2.5 surface preparation standard and shop primer application meeting PSPC requirements for corrosion protection during fabrication and transportation phases.
