Estimate before
you enquire.

A working sheet-weight calculator, pipe schedule and equivalent-grade charts, and a grade-selection reference — so your RFQ arrives already in the right ballpark.

Sheet Weight Calculator

Length × width × thickness × density

Density auto-fills from the selected grade.
Weight per sheet
46.36kg
Surface area  2.97
Weight per m²  15.60 kg/m²
Total for 50 sheets  2,318 kg
2.318 tonnes

Theoretical mass from nominal dimensions and standard density. Actual weight varies with tolerance and finish — treat as an estimate, not a billing figure.

Grade Selection Reference

Pick the grade by the environment

A quick orientation. For borderline cases — chlorides, high temperature, stress — talk to our desk before you commit.

Pipe Schedule Chart

Wall thickness by schedule

Nominal wall thickness (mm) per ASME B36.19M for stainless schedules. Tolerances apply — confirm against the mill certificate.

Equivalent Grades

Cross-standard grade map

Nearest equivalents across ASTM/AISI, UNS, EN (Euronorm) and JIS. Use for orientation; chemistry differs slightly between standards.
