Choose the Correct Cold Drawn Steel Buying Path

Start with the shape page when the drawing and dimensions control the purchase. Use a grade or application page when the governing standard, machining route or finished-component use is already known.

Buy by bar shape

Buy by material route

Buy by application or qualification need

Designation rule: AISI/SAE, ASTM, EN/DIN, JIS and GB names are search and procurement routes, not automatic substitution approvals. The purchase order must state the governing grade and product standard, delivery condition, testing and heat-specific MTC requirements.

Choose Steel Grade and Bar Shape Together

International buyers often search by a grade name plus round bar, flat bar, square bar or hex bar. Junxiong uses those terms as RFQ routes, not as proof that different national designations are identical or that every size is held in stock. Start with the required shape, then state one governing grade or product standard and the delivery condition.

Shape routes: round bar, flat bar, square bar, hex bar and drawing-defined profiles.

Buyer grade route Common search designations What Junxiong must confirm before quotation
Free-cutting and resulfurized machining carbon steel SAE 1117, SAE 1141, 1215, 12L14, 11SMn30, 11SMnPb30, 1.0715, 1.0718, SUM23, SUM24L, EN1A and SAE 1144 Exact standard, lead or restricted-substance requirement, shape, tolerance, machining route and heat-specific MTC. These designations are separate routes, not automatic substitutes. Use the free-cutting steel selector.
Carbon and bright steel C15 / S15C / SAE 1015 steel bars, C35 / S35C / SAE 1035 steel bars, EN3B / 070M20 bright steel bars, 1018 carbon steel bars, 1020 cold drawn carbon steel, SAE 1026 carbon steel bars, SAE 1040 / 1050 / 1060 carbon steel bars, 1045, C45, S45C and EN8 These names represent separate standards and limits. State chemistry standard, delivery condition, size, straightness and downstream heat treatment. Review the 1045 / C45 round-bar route where applicable.
Engineering alloy steel 4130 / 25CrMo4, 4140 / 42CrMo4, 40Cr / 5140 / 41Cr4 / SCr440, 4340 / 34CrNiMo6 / EN24, 8620 / 20NiCrMo2-2, 16MnCr5 / 20MnCr5 / SAE 5120 / 20Cr case-hardening steel and 6150 / 51CrV4 Ordered standard, annealed, normalized or quenched-and-tempered condition, hardness, decarburization, machining allowance and batch documents. Similar applications do not make these grade routes automatic substitutes.
Bearing steel 52100, 100Cr6, SUJ2 and GCr15 Do not approve substitution from a search alias. Confirm cleanliness, spheroidized-annealed or other condition, hardness route, surface quality and traceable MTC.
Stainless and precipitation-hardening steel 304, 316 / 316L, 17-4 PH / 630 / 1.4542 / SUS630, 430F / SUS430F / 1.4104 and 440C / 1.4125 / SUS440C Exact stainless grade, heat-treatment condition, corrosion or hardness requirement, shape, finish and governing bar standard. Review the stainless bar and profile route.

Acceptance rule: the purchase order, controlled drawing, agreed product standard, delivery condition and heat-specific MTC govern supply. Similar international designations may be comparison starting points, but they are not automatic equivalents.

Product Standards and Material Routes

  • SAE J403_202402: an SAE source for carbon-steel chemical-composition designations when the buyer orders an SAE grade.
  • ASTM A108-24: the active ASTM product specification for carbon and alloy cold-finished steel bars.
  • BS EN 10277:2018: technical delivery conditions for bright steel products when the purchase route uses an EN designation.
  • ASTM A276/A276M-25: an ASTM route for stainless steel bars and shapes; it does not apply to carbon-steel orders.

Procurement boundary: these standards cover different material and product routes and are not interchangeable. The RFQ and purchase order must identify the grade standard, applicable cold-finished or bright-bar product standard, shape, dimensions, tolerance, delivery condition, testing and heat-specific MTC. Publisher links are reference sources, not certificates for a Junxiong production heat.

Applications

  • CNC machining parts, shafts, pins and guide parts
  • Fasteners, nuts, bolts and threaded components
  • Mechanical fixtures, tooling and industrial hardware
  • Custom parts where machining cost should be reduced
