Is Sanmei Metal the right supplier for you?

We supply stainless steel together with the processing and technical support that projects and products need.

A good fit if you

Need a specific grade, finish or size for a project, from samples or one coil to a few containers
Want it slit, cut to size or fabricated to your drawing
Need documents: a Mill Test Report with every order, SGS testing on request
Want help choosing the right grade and finish for your application
Build products or projects: equipment housings, architectural interiors, elevator and kitchen work

When buying direct from a mill may suit you better

You need standard grades in full-mill quantities and compare on price per tonne
You need no slitting, cutting, documents or technical support
You already have a fixed spec and a mill allocation

Why choose 436 stainless steel?

Molybdenum and niobium take 430 further.

Corrosion resistance

Excellent against the atmosphere and fresh water; molybdenum improves it over 430. Less suited to most salts and seawater.

Heat resistance

Resists oxidation up to about 815 °C (1500 °F).

Weldability

Resistance welding, brazing and fusion welding all work; niobium stabilization protects the weld zone.

Formability

Stretches and forms easily. Niobium greatly reduces roping, or ridging, during forming.

Corrosion, heat and the shop floor.

How 436 behaves in service and in fabrication.

Corrosion resistance

Like 430, with better resistance to stress corrosion cracking.

Heat resistance

Good oxidation resistance up to about 815 °C.

Machining

Good machinability, similar to carbon steel.

Welding

All standard methods, including resistance welding and brazing.

Hot working

816–1093 °C (1500–2000 °F); anneal afterwards.

Annealing

788–899 °C (1450–1650 °F), then slow cooling.

Cold working

Cold works, with more force than austenitic grades.

Hardening

Cannot be hardened by heat treatment; cold work hardens it slightly.

436 or another grade?

How 436 compares with 430 and 434.

436 vs 430

436 adds molybdenum and niobium, for better corrosion resistance and weldability.

436 vs 434

436 is the niobium-stabilized version of 434. Niobium, at 5×C to 0.80%, improves resistance to ridging during forming.

Applications

Automotive trim and exhaust systems, exterior parts of home appliances, and interior and exterior architectural trim.

436 stainless steel FAQ.

Questions buyers ask before ordering 436.

Is 436 magnetic?

Yes. It is ferritic and magnetic, both annealed and cold rolled.

Is 436 better than 430?

For corrosion resistance and weldability, yes: its molybdenum and niobium give it the edge.

Can 436 be used in seawater?

It is not a good choice for seawater or most salts. Its strength is atmospheric and fresh-water corrosion.

What sizes do you supply?

Coil in 1000, 1219, 1240 and 1500 mm widths or slit to size, 0.15–3.0 mm thick. Sheet in the same widths, 2000 to 3048 mm long, 0.3–3.0 mm thick.

Our Leading Coating Technology.

Thicker coating, consistent color and easy-clean surfaces. Each one measured in our own production and compared with typical market product.
PVD coating

Thicker PVD coating

0.30µm
Typical coating thickness, up to 28% thicker than a typical market coil, so the color lasts longer.
See the coating test
Color control

Consistent color

ΔE ≤ 2
Every coil is held below the color difference the eye can see, so panels from different batches match.

Anti-fingerprint

Fingerprint-resistant

215solvent rubs
Our anti-fingerprint coating withstood 215 rubs with a strong solvent. The standard requires 100. Typical market AF failed at 70.
