| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |

What is SC410?
SC410 is the lowest strength tier of the JIS G5101 general-purpose carbon steel casting series, specified at 410 MPa minimum tensile strength and typically supplied at 245 MPa yield, 450 MPa tensile, 24 % elongation and about 130 HB (72 HRB). Its low carbon content gives good weldability and forgiving weld repair, so it is used for sand- and shell-cast valve bodies, pump casings and machinery housings in service up to about 425 °C, in F, SR, annealed, normalized, N+T and QT conditions. It has no corrosion resistance of its own and must be coated, and strength is modest; its tier corresponds to ASTM WCA, with SC450 the direct step up. SC410 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). SC410 has a yield strength of 245 MPa (35.5 ksi) and a tensile strength of 450 MPa (65.3 ksi) — weaker than 95% of steel grades. Elongation at break is 24% and the elastic modulus is 205 GPa (29.7 Msi).

Working with SC410
Is SC410 easy to machine?
Machines like ~0.3 %C carbon steel (≈65 % of AISI 1212); anneal or normalize first and expect hard skin/sand inclusions on unblasted surfaces.
Can SC410 be welded?
Readily weldable by SMAW/GMAW/SAW with E70xx-class consumables; preheat 100–150 °C on heavy sections and stress relieve at 600–650 °C after major weld repair.
Can SC410 be formed, bent or molded?
Sand- or shell-cast with generous risering (long freezing range, ~2 % solidification shrinkage); design 3–5 mm min wall and avoid abrupt section changes to prevent hot tears.

What surface finishes work on SC410?
Shot blast to SA 2.5 then prime/paint, zinc-rich coat, phosphate or zinc/nickel plate — bare surfaces rust quickly; not anodizable.

SC410 — frequently asked
What is SC410 used for?
SC410 is typically used for valve bodies, pump casings, machinery housings and flanges. In short: most weldable JIS cast steel; WCA strength tier; lowest-strength SC grade.
What is the yield strength of SC410?
SC410 has a typical yield strength of 245 MPa (35.5 ksi) and a tensile strength of 450 MPa (65.3 ksi) — weaker than 95% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is SC410 easy to machine?
Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Machines like ~0.3 %C carbon steel (≈65 % of AISI 1212); anneal or normalize first and expect hard skin/sand inclusions on unblasted surfaces.
Can SC410 be welded?
Yes — weldability is rated very good (78/100). Readily weldable by SMAW/GMAW/SAW with E70xx-class consumables; preheat 100–150 °C on heavy sections and stress relieve at 600–650 °C after major weld repair.

What is the maximum service temperature of SC410?
SC410 is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SC410-N and SC410-QT?
N is the default condition — standard commercial delivery condition: refines the as-cast grain, gives the best strength/toughness balance at the JIS minimums. QT: optional upgrade for thinner sections needing higher yield and wear resistance than the JIS minimum class. Yield strength is 245 MPa in N versus 360 MPa in QT.
