4. What standards and certifications do these nickel alloy sheets meet?
ASTM B162/B168/B622/B443/B444/B435/B435/B366 – Standard specifications for nickel and nickel alloy sheets and plates
ASME SB162/SB168/SB622/SB443/SB444/SB435 – For high-temperature, high-pressure, and structural applications
ISO 9001 certified production ensures consistent quality, traceability, and reliable chemical and mechanical properties.
5. How should these sheets be handled and stored?
Store in a clean, dry, ventilated area to prevent surface oxidation or contamination.
Avoid prolonged contact with strong acids or reducing agents unless compatible with the alloy.
Clean surfaces before fabrication to remove oil, dust, or residues.
Handle carefully to avoid scratches, dents, or bending.
Regular inspection is recommended when sheets are used in corrosive or high-temperature service.
