Which Stainless Steel Grades Should Buyers Choose?

The correct stainless steel grade depends on machining, corrosion resistance, magnetic behavior, strength and cost requirements. The following guide is for early sourcing discussion only.

304 stainless steel: general-purpose stainless steel bar for common corrosion resistance and industrial components.
201 stainless steel: often searched as a lower-nickel alternative for selected flat, square or profile applications.
303 stainless steel: free machining stainless steel for CNC turning and automatic lathe parts.
430 stainless steel: ferritic stainless steel, often searched by buyers needing magnetic stainless steel or cost-sensitive stainless flat/square material.
430F stainless steel: free machining ferritic stainless steel for machined components, round bars and hex bars.
416 stainless steel: free machining martensitic stainless steel for shafts, fittings and screw-machine parts.
316 / 316L stainless steel: often requested when corrosion resistance is more important than cost.

FAQ for Stainless Steel Bar and Profile Buyers

Can Junxiong supply 304 stainless steel cold drawn bars?

Yes. Junxiong can review 304 stainless steel cold drawn round bars, flat bars, square bars, hex bars and selected custom profiles. Please send the required standard, size, tolerance, length and quantity.

Can you supply 430F or SUS430F stainless steel bars?

430F / SUS430F stainless steel bars can be reviewed for free machining applications such as automatic lathe parts, fittings, fasteners and small machined components. Final grade confirmation should follow the buyer’s standard and MTC requirement.

Is 430 stainless steel the same as stainless iron?

Many buyers informally call 430 stainless steel “stainless iron” because it is ferritic and magnetic, but professional inquiries should use grade names such as 430, SUS430, UNS S43000 or EN 1.4016.

What stainless steel grades are suitable for CNC machining?

303, 430F and 416 are commonly searched for free machining stainless steel applications. 304 can also be machined, but buyers should confirm machining difficulty, tolerance, surface and tool life requirements.

Can Junxiong produce custom stainless steel profiles?

Custom stainless steel profiles can be reviewed when the buyer provides a section drawing, sample photo, grade, tolerance, length and quantity. Tooling feasibility depends on section shape and order volume.

Can different national grade names be substituted automatically?

No. Grade names such as AISI, UNS, EN, DIN, JIS and GB are useful for search and initial sourcing, but final substitution must be confirmed by chemical composition, mechanical properties, buyer standard and MTC requirement.

What information is needed for a stainless steel quotation?

Please provide grade, standard, shape, size, tolerance, length, quantity, surface condition, application, destination country and required documents.

Can Junxiong provide export packing and material documents?

Export packing, MTC, heat number and selected inspection requirements can be reviewed before production according to order requirements.
