Description
Product details
This product line covers industrial-grade sheets and plates manufactured to rigorous international standards (ASTM, ASME, AISI) for pressure vessels, structural fabrication, storage tanks, and extreme-environment liners. [1, 2, 3] ## 📐 Technical Classification: Sheets vs. Plates * Sheets: Typically under 6mm (1/4“) thick, supplied in cold-rolled or hot-rolled finishes, ideal for precision forming and cladding. * Plates: Typically 6mm (1/4”) and thicker, designed for heavy structural welding, boilers, and high-load mechanical applications. [4, 5, 6, 7, 8] ------------------------------ ## 📋 Material Specifications & Design Standards## 1. Stainless Steel (Corrosion Resistant & Sanitary) [9] * Standards: ASTM A240 / ASME SA240 (Pressure vessel and general service specification). * Standard Austenitic: 304 (General utility), 304L (Low-carbon to prevent weld decay), 304H (High-temperature strength). * Marine & Chemical Grade: 316 (Superior pitting resistance), 316L (Low-carbon), 316Ti (Titanium stabilized for high-temp chemistry), 317, 317L (Severe acid handling). * High-Temperature & Alloys: 310, 310S (Resists oxidation up to 1100°C), 321, 321H (Intergranular corrosion resistance for aerospace and exhaust setups). [10, 11, 12] ## 2. Carbon Steel (Boiler & Structural Grade) * Standards: ASTM A515 / A516 (For intermediate and higher-temperature service in welded pressure vessels). * Grades 60 & 70: Grade 70 provides higher tensile strength; Grade 60 offers excellent notch toughness for moderate/lower-temperature service. * IS 2062 (B 2062): Standard structural steel specification for general engineering and infrastructural fabrication. [13, 14, 15] ## 3. Alloy Steel (Chrome-Moly / Power Generation) * Standard: ASTM A387 (Chromium-Molybdenum alloy steel plates for elevated-temperature pressure vessels). * Grades: 1, 5, 9, 11, 12, 22. * Classes: Class I (Standard tensile properties) and Class II (Higher tensile strength via accelerated heat treatment), used extensively in oil refineries and chemical plants. [16] ## 4. Nickel & Exotic Alloys (Extreme Chemicals & Aerospace) * B162 (Nickel): Pure commercial nickel plates for caustic soda processing. * B127 (Monel 400): Exceptional resistance to hydrofluoric acid and marine environments. * B463 (Alloy 20): Formulated specifically to withstand sulfuric acid. * B576 (Hastelloy C-276): Top-tier resistance to aggressive pitting and crevice corrosion. * B168 / B443 (Inconel 600 / 625): Excellent mechanical strength and oxidation resistance at extreme temperatures. ## 5. Copper & Non-Ferrous Alloys (Electrical & Thermal) * Materials: Aluminium, Pure Copper, Brass, and Gunmetal. * Applications: Electrical busbars, heat exchanger tubesheets, non-sparking structures, and decorative architectural paneling.
