Manufacturer Custom 316L 1.4404 Stainless Steel Plate Sheet Hot Rolled Cold Rolled 2B No.1 Corrosion Resistant Marine Grade Metal Plate

316L / 1.4404 Stainless Steel Plates and Value-Added Processing ServicesIn-House Stock Inventory · Full-Process Value-Added Fabrication · Serving Global High-End Industrial and Structural Engineering
In chemical processing, marine engineering, water treatment, pressure equipment, and high-end infrastructure, the value of material supply has long gone beyond simply “providing a steel plate.”
What truly affects project efficiency and risk is whether the material grade matches the service conditions, whether plates can be delivered quickly, whether cutting and beveling accuracy remain consistent, whether welding quality can be fully traced, and whether the supplier can integrate the complete manufacturing process from raw material to finished components.
Peak Kong Special Steel (煌港特鋼有限公司) focuses on 316L / 1.4404 austenitic stainless steel plates and has established a one-stop service system covering in-stock inventory, precision cutting, beveling, welding and assembly, and non-destructive testing (NDT).
We provide reliable, flexible, and traceable plate-processing solutions for high-end industrial and structural engineering projects worldwide.
From stocked stainless steel plates to engineered components — shortening the supply chain and improving manufacturing efficiency, allowing materials to deliver real engineering value.
1. 3 mm–100 mm In-Stock Plates for Rapid Engineering ResponsePeak Kong Special Steel maintains in-house inventory of 316L / 1.4404 medium and heavy stainless steel plates, covering commonly required thicknesses from approximately 3 mm to 100 mm, helping customers reduce the time costs associated with production scheduling and long procurement cycles.
Standard Plate Dimensions1500 × 6000 mm
2000 × 6000 mm
2000 × 8000 mm
Other special plate dimensions can be evaluated according to project requirements.

The in-stock supply model is particularly suitable for:
Engineering maintenance and replacement projects.
Emergency spare parts and shutdown maintenance.
Small-batch and multi-specification orders.
Non-standard equipment manufacturing.
Prototyping, samples, and project pilot stages.
Engineering projects requiring rapid material cutting and preparation.

The actual material grade, thickness, dimensions, quantity, and delivery schedule will be confirmed according to inventory availability and project requirements.
2. 316L / 1.4404: A Reliable Material Base for Corrosive Environments316L / 1.4404 is a low-carbon austenitic stainless steel offering good corrosion resistance, weldability, and fabrication adaptability. It is widely used in coastal, humid, chemical processing, water treatment, food processing, pharmaceutical, and other demanding environments.
Key Material BenefitsGood adaptability to various humid and coastal atmospheric environments.
Good corrosion resistance in certain chloride-containing media.
Its low-carbon composition helps reduce the risk of intergranular corrosion after welding under appropriate conditions.
Good cutting, forming, and welding characteristics.
Suitable for tanks, equipment enclosures, supports, and structural components.
May reduce maintenance requirements associated with certain coating and surface-protection systems.

Material selection should nevertheless be evaluated according to the actual service medium, chloride concentration, operating temperature, pressure, stress conditions, and intended design life.
For extremely corrosive environments, Peak Kong Special Steel can also assist in evaluating duplex and super duplex stainless steel alternatives.
3. From Plate Supply to Precision Cutting — Improving Manufacturing EfficiencyPeak Kong Special Steel goes beyond conventional stainless steel plate trading by integrating in-stock warehousing with precision fabrication capabilities, providing customers with a complete service chain from raw material to semi-finished and finished components.
1. Laser CuttingSuitable for thin plates, medium and heavy plates, and components with complex contours, offering:
High-precision contour cutting.
Relatively small heat-affected zones.
Suitable for holes, flanges, and complex geometries.
Processing according to engineering drawings and digital models.

2. Waterjet CuttingWaterjet cutting is suitable for heat-sensitive components, thicker materials, and applications where thermal distortion needs to be minimized.
Applications include:
Heavy and extra-heavy plate cutting.
Large irregular components.
Precision hole and contour cutting.
Engineering components with strict thermal-impact requirements.

3. Plasma CuttingSuitable for high-efficiency cutting of medium and heavy plates and large structural components. It can be combined with subsequent machining, beveling, and welding assembly.
4. Cutting According to Drawings and ModelsCustomers can provide:
2D CAD drawings.
3D models.
Parts lists.
Material and thickness requirements.
Tolerance and surface-finish requirements.

Peak Kong Special Steel can perform nesting, cutting, marking, and batch management according to engineering drawings, helping reduce secondary processing on site and minimize material waste.
4. Professional Beveling for High-Quality Welding PreparationBevel geometry directly affects weld penetration, filler-metal consumption, welding distortion, and weld quality.
For medium, heavy, and extra-heavy plates, precise and consistent bevel preparation is a critical step in ensuring reliable subsequent welding.
Peak Kong Special Steel can provide various structural welding bevel configurations, including:
V-groove.
X-groove.
U-groove.
K-groove.
Compound bevels.
Special bevels specified by engineering drawings.

Key Beveling CapabilitiesStable bevel angles.
Controlled root-face dimensions.
Good surface finish.
Reduced variation in welding assembly gaps.
Reduced filler-metal consumption and rework costs.
Preparation for high-standard welding and inspection.

The bevel configuration, angle, root face, and root gap will be determined according to plate thickness, joint configuration, welding method, and approved welding procedure documentation.
5. Welding and Finished-Component Assembly — From Plate to ComponentFor chemical processing equipment, environmental protection systems, marine structures, and non-standard industrial equipment, purchasing stainless steel plates alone often leaves customers with substantial additional work involving cutting, fit-up, welding, and inspection.
Peak Kong Special Steel can undertake:
Stainless steel prefabricated components.
Non-standard equipment structural components.
Heavy-plate welded assemblies.
Equipment bases and support frames.
Flanges, reinforcement plates, and connection plates.
Tank and tower components.
