Product Overview

What are IRS350 Coils for CR / AISI IRS350 C Coils

IRS350 CR Coils, also called IRS350 AISI CR Coils, are stainless steel cold rolled coils designed to provide an array of strength, formability and resistance to corrosion. The cold rolling process enhances the surface finish, dimensional precision and mechanical properties, making these coils suitable for precise fabrication and structural applications. They are commonly used where controlled size, smooth finishing and high-quality performance are needed.

Frequently Asked Questions

Quick answers to common queries about IRS350 CR Coils.

SS IRS350 CR coils are cold-rolled ferritic stainless steel coils designed for high-strength structural use with good corrosion resistance and formability per Indian Railway specifications.
Thicker IRS350 CR coils cost more because they contain more material and require additional rolling, annealing, and handling during production.
Wider or non-standard coil sizes generally increase the price due to greater raw material use and more complex mill setup and handling.
Yes, smoother or speciality finishes raise costs because additional cold-rolling, annealing, and surface processing steps add labour and inspection expenses.
Fluctuating prices of steelmaking elements like iron and chromium directly impact IRS350 CR coil costs since raw-material costs form the bulk of the product price.
IRS350 CR coils are uniquely suited for heavy-duty, maintenance-free structural components in railway rolling stock and other built-to-last transport structures due to their strength-to-weight balance and atmospheric corrosion resistance.
