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

Sulfuric acid, chemical, aggressive environments

Common questions

01What is the density of 904L?
8000 kg/m³ — the figure the weight calculators on this site use for 904L. The value is Outokumpu / stainless technical resources’s.
02What is the chemical composition of 904L?
C ≤ 0.02, Si ≤ 1, Mn ≤ 2, P ≤ 0.045, S ≤ 0.03, Cr 19–23, Ni 23–28, Mo 4–5, N ≤ 0.1, Cu 1–2, in mass %, to ASTM A240 / UNS N08904. An element the standard sets no requirement for is left blank here rather than written as zero.
03What is 904L used for?
Sulfuric acid, chemical, aggressive environments
