ASTM A242 Type 1 Corten Steel Plate is a hot-rolled, high-strength low-alloy structural steel plate that resists atmospheric corrosion through its nickel, chromium, and copper content. When exposed to weather, these elements combine with atmospheric conditions to form a self-protecting layer on the surface, allowing the plate to remain stable without additional coating in most environments.
Delivered in structural condition for high-temperature working applications, it is widely used where corrosion resistance, strength, and weldability must all be present in a single material.
ASTM A242 Type 1 Plates are applied wherever structural steel must combine corrosion resistance with high-temperature working capability. Common application areas include:
ASTM A242 Type 1 Plates are important because they deliver atmospheric corrosion resistance without sacrificing structural strength or weldability. This combination reduces material failure risk in demanding industrial environments like petrochemical and oil and gas facilities, where downtime from corrosion-related maintenance directly impacts operational cost and safety.
ASTM A242 Type 1 and ASTM A606 Type 2 are both corten steel grades, but they differ in alloy composition and typical use case. ASTM A242 Type 1 contains chromium in addition to copper and nickel, giving it stronger performance in high-temperature and heavy industrial environments such as petrochemical, oil and gas, and pulp and paper processing. ASTM A606 Type 2, by contrast, is more commonly selected for architectural and structural applications like bridges, roofing, and towers, where weathering appearance and outdoor exposure resistance are the priority. Both grades are available from Conquest Steel & Alloys — our team can help identify which grade fits your specific application and operating conditions.

Conquest Steel & Alloys, based in Delhi, is a leading manufacturer and supplier of ASTM A242 Type 1 Corten Steel Plates, serving petrochemical, pharmaceutical, oil and gas, pulp and paper, and structural fabrication industries across India and international export markets. Plates are manufactured to national and international quality standards, with dimensions, surface finish, and end finish customized per client cut-made specifications.
Before dispatch, every batch undergoes material testing, including hardness, hydrostatic, ultrasonic, flaring, and flattening tests, to confirm quality compliance. Plates are packed according to client expectations to prevent damage during domestic transit or international export shipment. With a pan-India service network and established export capability, Conquest Steel & Alloys supports both bulk industrial orders and project-specific custom requirements.
1. What makes ASTM A242 Type 1 Plates corrosion-resistant?
The nickel, chromium, and copper content in the alloy forms a self-protecting layer on the surface when exposed to atmospheric conditions, providing ongoing corrosion resistance.
2. What industries use ASTM A242 Type 1 Corten Steel Plates?
Petrochemical, pharmaceutical, oil and gas, pulp and paper, and heat treatment industries commonly use these plates for their combination of strength and corrosion resistance.
3. What thickness range does Conquest Steel & Alloys supply?
We supply ASTM A242 Type 1 Plates in thicknesses from 0.8mm to 50mm, widths from 750mm to 1500mm, and lengths from 2500mm to 12000mm.
4. What quality tests are performed before dispatch?
Every batch undergoes hardness, hydrostatic, ultrasonic, flaring, and flattening tests to verify quality before it leaves the manufacturing unit.
5. Does Conquest Steel & Alloys export ASTM A242 Type 1 Plates internationally?
Yes. In addition to pan-India supply, our plates are exported to global markets for use across various industries.
6. How is ASTM A242 Type 1 different from ASTM A606 Type 2?
ASTM A242 Type 1 contains chromium and is typically used in heavy industrial and high-temperature applications, while ASTM A606 Type 2 is more common in architectural and structural applications like bridges and towers.
