Product Change – Increased Customer Profits

Case Study

A large refrigeration tubing company needed to increase the line speeds of their ERW tube mills to improve productivity and profitability. By utilizing VA/VE principles, ISC was able to leverage Interstate Steel Company’s global sourcing capabilities combined with our in-house metallurgical expertise to develop an off-shore specialty cold rolled steel. This “superior steel grade” recovers, re-crystallizes and grows grains much quicker during the customer’s annealing process than previously thought possible. This single grade modification allowed our customer’s line speeds to more than double and in doing so improved their bottom line by more than $1 million annually.
