mass %. A blank cell means the standard sets no requirement for that element, not zero. Single values are limits: "≤" a maximum, "≥" a minimum.
Reference values from the cited standards. They describe what the standard requires, not a specific heat of material; the mill test certificate governs what is delivered.
Typical applications
High temperature, pressure equipment
Common questions
- 01What is the density of 347?
- 8000 kg/m³ — the figure the weight calculators on this site use for 347. The value is Outokumpu / stainless technical resources’s.
- 02What is the chemical composition of 347?
- C ≤ 0.08, Si ≤ 0.75, Mn ≤ 2, P ≤ 0.045, S ≤ 0.03, Cr 17–19, Ni 9–13, in mass %, to ASTM A240. An element the standard sets no requirement for is left blank here rather than written as zero.
- 03What is 347 used for?
- High temperature, pressure equipment
