Inconel 825, SS 904L, super duplex, Hastelloy, Monel and carbon steel in every form a process plant needs — with the right ASTM or ASME standard on the certificate, and a quotation back within one working day.
Most of our enquiries are for these two. Each has a full page for every product form — standards, sizes, weights, price factors and the questions buyers ask.
The nickel–iron–chromium alloy with molybdenum, copper and titanium that refineries, fertiliser plants and sour-gas lines choose when chlorides would crack stainless steel.
The super-austenitic stainless steel with copper for dilute sulphuric and phosphoric acid and chloride-bearing cooling water — the step up from 316L before you move to nickel alloys.
Every tile is a grade we supply. Choose a product and the table shows only the grades we can offer in it — then one click takes you to that exact product page with its standards, sizes and weights.

Six high-intent routes — 825 sheet and plate, fittings and flanges, 718 flanges (as specified), 904L plate, and 625 fasteners — each with standard, grade and guide links.
Also in fasteners: Super Duplex 2507 studs and nuts.
Every type has its own page explaining how it is made, which dimensional standard it follows and which grades it comes in. Start with a featured engineering product if you already know the grade and form.
Flat product under 3/16" (4.76 mm) thick, cold rolled in most grades, supplied in finishes from 2D and 2B to BA and mirror.

Both are chosen for sulphuric and phosphoric acid. Inconel 825 carries about 42% nickel and titanium, so it resists chloride stress-corrosion cracking and sour service far better; SS 904L is a super-austenitic stainless steel with about 25% nickel that costs less and suits milder duty. The choice is driven by chlorides, temperature and H₂S.
Grade, standard, size, quantity and delivery country are all we need to start. Material lists and drawings are welcome — send them on WhatsApp or email them to sales@kanaksteeleng.com.
