This is the tools library from Nandini Steel, an ISO 9001:2015 certified stainless, nickel-alloy and pressure-vessel steel supplier in Mumbai since 2003. Weight, grade selection and cross-reference tools built around the grades we hold ex-stock.
Written and reviewed by our engineering team. Browse the topics below, or send a spec and we will point you to the right grade and standard.
Metal weight calculator
Estimating weight before you order is the single most useful step in planning freight, confirming a mill minimum, or checking a quoted price against the material content. Our metal weight calculator covers sheet, plate, coil, pipe and round bar across stainless, nickel-alloy and carbon steel grades. Enter the form, dimensions and grade, and it returns the weight using the standard density for that alloy, drawn from the same weight and size charts we use internally to confirm dispatch quantities. For plate and sheet this means thickness, width and length; for pipe it means outside diameter, wall thickness and length; and for round bar it means diameter and length. It is built for quick checks at the quotation stage, not as a substitute for the final weight on your mill test certificate, and our plate weight calculation guide and stainless steel weight chart walk through the same arithmetic by hand if you want to verify a figure.
Steel grade selector
Choosing between 304, 316, 904L, Incoloy 825 and the rest of the catalogue comes down to a handful of service variables: chloride exposure, temperature, acid concentration and whether the part will be welded. The grade selector tool asks for these conditions and returns a recommended grade along with the standard it should be ordered against, following the same logic our engineering team uses when reviewing an RFQ. It is a starting point for narrowing the field, and our guide to selecting a stainless grade walks through the reasoning in more depth if you want to check the recommendation yourself before you order.
UNS, Werkstoff and JIS cross-reference
International projects routinely specify a grade by a different numbering system than the one on our stock sheet, and a mismatch between systems is a common source of receiving-inspection disputes. Our UNS, Werkstoff and JIS cross-reference maps the designation systems most frequently seen on drawings and purchase orders, for example confirming that Incoloy 825 corresponds to UNS N08825 and Werkstoff number 2.4858, so a buyer working from a European or Japanese specification can confirm they are ordering the grade they intend. The same page cross-references AISI and EN designations for the stainless grades, which is useful when a drawing from a European client lists an EN number such as 1.4401 for 316 and your purchasing team needs the ASTM equivalent to place the order.
Working with indicative results
Every number these tools return, whether weight, grade recommendation or cross-reference, is indicative and intended to speed up planning, not to replace the mill test certificate or the engineering review behind a confirmed order. Actual plate, sheet and coil weight varies within standard mill thickness tolerance, and a grade recommendation always needs confirmation against your full service conditions. Run your numbers through the calculator or selector, then send the result through an RFQ and our engineering team will confirm the final figures against your exact order before dispatch.
