The most widely used structural steel in India. IS 2062 E250 is a hot-rolled low carbon steel with good plasticity, toughness, and weldability. Available in plates, HR sheets, and sections across Chennai steel yards. Sub-grades A, B, and C differ only in impact test temperature; sub-grade B (IS 2062 E250 B) is the standard mill supply.

IS 513 cold-rolled sheets offer a superior surface finish and tighter dimensional tolerances than hot-rolled stock. The low carbon content makes them ductile and easy to form, stamp, and weld. CR1 is general purpose; CR2 is drawing quality; CR3 is deep drawing; CR4 is extra deep drawing (EDD). All grades carry ISI mark and are available skin-passed or bright annealed.

IS 2062 E350 is a high tensile structural steel with 40% higher yield strength than E250, making it the go-to for load-bearing fabrications where reducing weight or section size matters. IS 8500 covers weldable structural steels in similar strength ranges. Used extensively in Indian crane, conveyor, and heavy machinery fabrication.

The most widely specified stainless steel globally. Its 18% chromium and 8–10% nickel composition delivers excellent corrosion resistance in most environments. Not susceptible to intergranular corrosion in the as-welded condition unless heated in the sensitisation range (450–850°C). The IS 6911 designation 04Cr19Ni9 reflects carbon ≤ 0.04%, 19% Cr, 9% Ni — identical chemistry to the EN/AISI 304 you may know from overseas suppliers.

The addition of 2–3% molybdenum to SS 304's chemistry elevates chloride pitting resistance dramatically — essential for coastal and marine environments across India's long coastline. The "L" (low carbon, ≤0.03%) prevents sensitisation in welded joints without post-weld annealing. Specified for anything exposed to seawater, salt fog, or aggressive cleaning chemicals.

A chromium-only (nickel-free) ferritic stainless steel. SS 430 is magnetic, lower cost than 304, and has good oxidation resistance up to 870°C. It does not harden by heat treatment. Its lower nickel content makes it significantly cheaper — typically 30–35% less than 304 — while still delivering far better corrosion resistance than mild steel. Commonly used for decorative and general interior applications.

The most popular aluminium alloy for sheet metal fabrication. Magnesium (2.2–2.8%) as the primary alloying element provides high fatigue strength, excellent weldability (MIG/TIG), and superior resistance to seawater and atmospheric corrosion. Non-heat-treatable — strength is controlled by work-hardening (H-tempers). IS 737 Grade 51000 is the direct BIS equivalent of internationally known AA 5052.

The workhorse high-strength aluminium. The Mg-Si-Cu chemistry and T6 (solution heat treated + artificially aged) temper delivers the best strength-to-weight ratio among general engineering aluminiums. Machines beautifully, anodizes well, and welds with TIG/MIG — though note that the HAZ loses some T6 strength after welding. IS 733 HE20 covers extruded bar/section; IS 737 grade 63400 covers plate and sheet.

The strongest of the non-heat-treatable aluminium alloys. The 4–4.9% Mg content (plus Mn and Cr) gives 5083 exceptional strength while retaining outstanding weldability and the best seawater corrosion resistance in the 5xxx series. Cannot be used above 65°C in sustained service as Mg precipitation at grain boundaries reduces corrosion resistance.

The strongest commercially available aluminium alloy. Zinc (5.6–6.1%) as primary alloying element with Mg and Cu delivers structural steel-class strength at one-third the weight. Poor weldability limits use to bolted or riveted assemblies. T6 temper maximises strength; T73 (overaged) improves stress-corrosion resistance where the part is under sustained load. Widely used in Indian aerospace and defence.

IS 1897 Cu-ETP (Electrolytic Tough Pitch) copper strip and sheet is the standard for electrical applications — ≥99.9% copper purity with ≤0.04% oxygen delivers 100% IACS conductivity. IS 191 covers drawn copper sheets for general engineering. Cu-OF (oxygen-free) is used where hydrogen embrittlement must be avoided (welding, high-temp). Available annealed (O-temper) for forming or half-hard (H02) for busbars.

IS 410 covers three brass compositions. Grade 1 (70Cu:30Zn, Cartridge Brass) is the most ductile, ideal for deep drawing and cold forming. Grade 2 (63:37) balances formability and machinability. Grade 3 (60:40, Muntz Metal) has the highest strength and is the most machinable, widely used for turned components and engraved plaques. All grades resist dezincification unless in aggressive chloride environments (use dezincification-resistant CW602N/CW617N for those).

Cast acrylic (PMMA) is the benchmark laser-cut non-metal. CO₂ laser produces a flame-polished edge straight off the machine — no post-processing needed. Cast sheet (IS 6437) has better optical properties and chemical resistance than extruded; extruded is cheaper and has tighter thickness tolerance. Available in clear, opal, and 30+ solid colours. Excellent UV resistance means outdoor applications don't yellow.

Polycarbonate is 250× tougher than glass by weight and virtually unbreakable, making it the choice for safety glazing, machine guards, and bullet-resistant panels. Polypropylene (IS 10910) offers outstanding chemical resistance and is the go-to for acid tanks, trays, and laboratory furniture. HDPE is food-safe and moisture-resistant. Nylon PA6 offers self-lubricating properties for wear pads and bushings. All are laser-cuttable with CO₂ — edges are not fire-polished but smooth and clean.
