Standards and Inspection Guidance
- Common references include ASTM A36, ASTM A500, ASTM A513, SAE/AISI 1018, SAE/AISI 1020, IS 2062 and EN 10025 S235/S275/S355 where specified.
- Equivalent or alternate grades should be approved by the buyer, consultant or project engineer before quotation.
- For tube and hollow section enquiries, clarify whether the requirement is structural HSS, mechanical tubing or general pipe.
- State MTC, PMI, dimensional inspection, impact testing, marking, packing and third-party inspection requirements where applicable.
Mild Steel vs Carbon Steel vs Stainless Steel
Mild steel is usually selected for low-carbon fabrication and structural requirements, carbon steel covers a wider range of carbon and mechanical property grades, and stainless steel is selected where corrosion resistance is a key factor. Buyers should confirm the exact grade and standard before RFQ review.

Mild Steel Supply FAQs
Which mild steel grades does Rubinox handle?
Rubinox handles mild steel enquiries for grades and specifications such as ASTM A36, ASTM A500, ASTM A513, SAE 1018, SAE 1020, EN S235 and EN S355. Buyers should share the exact standard, grade, form, dimensions and delivery location.
What is the difference between mild steel and carbon steel?
Mild steel is generally used as a low-carbon fabrication and structural term, while carbon steel is a wider category that includes low, medium and higher carbon grades. Buyers should specify the exact grade or standard required.
Which mild steel grade is used for hollow sections?
ASTM A500 is commonly reviewed for structural hollow sections, while ASTM A513 is commonly reviewed for mechanical tubing. Final selection depends on section shape, wall thickness, standard and application.
Which mild steel grade is used for structural plates and sections?
ASTM A36, EN S235 and EN S355 are commonly reviewed for structural plates, sections and fabrication work. S355 is typically considered where the project specification requires higher structural strength than S235.
Which mild steel grade is used for machining?
SAE 1018 and SAE 1020 are commonly reviewed for general engineering, machining, bars, rods and machined blanks. Buyers should confirm finish, condition, tolerance and mechanical requirements.
What details are needed for a mild steel quotation?
Share grade, standard, product form, size, thickness, OD, wall thickness, length, section size, quantity, condition, documentation requirement and delivery location.
Can buyers request MTC, inspection or cutting support?
Buyers can mention MTC, PMI, dimensional inspection, cutting, marking, packing or third-party inspection requirements in the RFQ. Support is reviewed where applicable and as per requirement.
Can mild steel grades be substituted?
Equivalent or alternate grades should be used only when approved by the buyer, project engineer or end user. Chemistry, mechanical properties, standard and application duty should be checked first.
Can Rubinox review IS 2062 or EN S275 mild steel enquiries?
Yes. Rubinox can review IS 2062 and EN S275 mild steel enquiries when buyers share exact standard, grade or subgrade, product form, dimensions, quantity, condition and documentation scope. These references should not be treated as automatic substitutes for A36, S235 or S355 unless approved by the buyer or project specification.
Buyer Details to Confirm
