Industries Laxcon Steels serves

Laxcon Steels makes stainless, alloy and special steel long products: billets, blooms and ingots out of the melting shop, hot rolled bars and sections off four cross-country mills, and cold finished bar off the peeling, drawing and grinding lines. The sectors below are the ones those products are made for, with the families each one draws on.

Automotive and heavy vehicles

Round cornered squares are rolled for drop forging in the automotive industry: free of surface defects and cracks, uniform through the section, 100 percent ultrasonically tested, and used by forging shops to make flanges and fittings. They run 45 RCS to 100 RCS in lengths up to 8 metres.

Hot rolled round bars, 16 mm to 125 mm, go into engineering parts such as shafts, gears and axles, covering heavy trucks, agricultural equipment and the automotive market. Threaded bars serve automotive fastening, and HRAP unequal angles are in demand in the same sector, where support is needed on one side more than the other.

Oil, gas and offshore

Duplex steel is specified where high strength is needed, as in oil and gas. Its two-phase ferrite and austenite structure makes it about twice as strong as a standard austenitic or ferritic grade, with better toughness and ductility than the ferritics; Laxcon supplies 1.4462, 1.4410 and 2205 at PREN 18 to 35 against ASTM A182, A276 and A240.

Precipitation hardening steels, 15-5PH and 17-4PH, are listed for oil, gas, power, offshore, chemical and nuclear service, and for high pressure pump and valve components.

Laxcon holds NORSOK M-650 through TÜV India and Pressure Equipment Directive approval through TÜV NORD Systems. See quality.

Marine and shipbuilding

ABS has approved Laxcon's rolled bar facility and process for rolled bar for machinery components in marine applications. Lloyd's Register EMEA has approved the company as a manufacturer of steel plates, strip, sections and bars, covering steel making, semi-finished products and bars, and DNV has issued approval of manufacturer for rolled steel products. All three certificates are on the quality page.

Precision shaft quality bars are made for rotating duty including boat shafts. HRAP flat bars go into seawater systems, firewalls and blast walls, and cargo tanks, and threaded bars are used in marine fastening.

For coastal and chloride exposure the grade to specify is 316 rather than 304, because the molybdenum in 316 resists chloride pitting: the reasoning is set out in the equal angle guide.

Aerospace

Laxcon is certified to AS 9100 by DQS, alongside IATF 16949:2016.

Precipitation hardening steels are supplied for aerospace against AMS 5642, AMS 5622, DIN/EN 10088-3 and ASTM A564, in heat treatment conditions from solution annealed through H900, H925, H1025, H1075, H1100, H1150, H1150D and H1150M. Duplex bar is listed for aerospace as well as pulp and paper.

Construction and structural fabrication

HRAP equal angles, 20 × 20 mm to 125 × 125 mm, are made for metal construction, structural frames, brackets, chassis and machinery parts, in industrial and agricultural work. Unequal angles, 25 × 15 mm to 100 × 75 mm, cover the asymmetric cases.

Channels are rolled in both parallel (non-taper) and non-parallel (taper) form, 50 × 25 mm to 101.6 × 50.8 mm, for structural, architectural and industrial use, cut to size on request. HRAP flat bars, 20 mm to 150 mm wide, serve architectural and structural design components and bridges.

Threaded bars are used in construction fastening, and bright bars in engineering and construction where large structures need stability and strength.

General engineering and machining

Bright bars, 5 mm to 115 mm, cold drawn, centreless ground, peeled and polished, rough peeled or smooth turned, are held to h7 through h11 with a surface of Ra 0.2 micron and straightness up to 0.5 mm per metre. This is the standard stock for machining work.

Square bright bars, 12.70 mm to 55 mm, and cold-drawn flat bars, 20 mm to 100 mm wide at h11, carry the same finish into other sections.

Proof machined bars, 120 mm to 550 mm, are rough turned below the outer skin so the surface is proven clean and free of defects before the customer's final machining.

Fasteners

Hexagonal bright bars, 16 mm to 55 mm across flats, are drawn for nuts, valves, hose ends, fasteners and hex bolts.

Threaded bars are rolled M 6 to M 45, fully threaded to ANSI B1.1 class 2A fit, in A2/304 and A4/316 classes 50, 70 and 80 and B8/B8M classes 1 and 2, with both ends checked on a GO/NOGO gauge.

Pumps, valves and rotating equipment

Precision shaft quality bars, 8 mm to 81 mm, are made for rotating duty: pump shafts, cylinder shafts, boat shafts, piston shafts, valve shafts and bearing bars. They are rated at 75 ksi, with 304 shafting at 100 ksi tensile strength available, held to h7, h8, h9, j6, f7 and f8 with straightness of 0.015 inch TIR per 10 feet. Every bar is checked for ultrasonic flaws and packed with distance rings inside plywood boxes.

Precipitation hardening steels cover high pressure pump and valve components and measuring and control parts.

Chemical, process and power plant

HRAP flat bars are used across the chemical industry, in heat exchangers, fuel gas cleaning and cargo tanks. Duplex bar goes into heat exchangers and into storage and exchange equipment in high pressure and saline service.

Precipitation hardening steels are listed for power, chemical and nuclear service, for pulp and paper, and for mechanical and welded components.

Laxcon is recognised as a Well Known Steel Maker by the Central Boilers Board, and holds IS 17875:2022, IS 6603:2001, IS 14650:2023 and IS 15997:2012 from the Bureau of Indian Standards.

Pharmaceutical, food and beverage

HRAP flat bars are supplied to pharmaceutical plants and to kitchen equipment makers, and precipitation hardening steels are listed for the food industry.

In food processing and clean room work stainless sections are chosen for corrosion resistance under repeated washdown with water and detergents; the reasoning is set out in the equal angle guide.

Forging shops and re-rollers

Forging quality ingots, available up to 22,000 kg a piece in square, fluted and round formats, are cast for direct upsetting, open die forging, ring rolling, flanges and re-rolling. Every piece is marked with heat number, colour code, grade, size and weight.

Continuous cast billets and blooms, 120 mm to 300 mm square, rectangular or round and up to 8.5 metres, feed rolling, hot forging and ring rolling. RCS bars are the drop forging feed.

Furniture and architectural fit-out

T-profile, also called T-patti, seals and finishes edges where two components join, on worktops, wall panels and similar work. It is made for good weldability and corrosion resistance and supplied up to 6.4 metres.

Channels are rolled for architectural as well as structural use.

Railways, renewable energy and defence

Laxcon names railways, renewable energy and defence among the industries it supplies, alongside the sectors above; see about. Material for them is drawn from the same catalogue and specified by grade, profile and size.

An enquiry for a sector not listed here carries the same three parameters: grade, profile and size. They can be sent to sales@laxconsteels.com or through the enquiry form.
