Cold Rolled Lamination Steel

Lamination specialties is a full service supplier of electrical steel since 1956 specializing in grain oriented go non grain oriented ngo and cold rolled motor lamination crml.

Cold rolled lamination steel.

Electrical steel is usually manufactured in cold rolled strips less than 2 mm thick. Cold rolled steel has been rolled at room temperature below its recrystallization temperature which enables better control over finished product shape thickness dimensions and surface finish. Ease of stamping and low tool wear help to contribute to the low cost of finished laminations. It is a semi processed sp material produced via batch annealing and temper rolling rather than on dedicated continuous decarburizing and annealing lines as emphasized in fig.

1 1 this specification covers cold rolled carbon sheet steel used for magnetic applications. Crml is an electrical grade of steel containing low amounts of alloy. Electrical steel lamination steel silicon electrical steel silicon steel relay steel transformer steel is an iron alloy tailored to produce specific magnetic properties. Crml steel development was enabled by improvements to the production practices for low carbon cold rolled steel.

Cold rolled motor lamination crml astm a726. Our crml meets astm a726 standards for use in the electromagnetic core of fractional motors and other electrical equipment and components. Carbon steel should be considered for applications where. Cold rolled transformer steel laminations non oriented transformer core laminations id 10475949.

1 integrated mills lacking the specialized continuous annealing lines required for noes were provided. These include electric motors generators and transformers. Small hysteresis area resulting in low power loss per cycle low core loss and high permeability. These products commonly called cold rolled magnetic lamination steel crml are usually intended for applications in which the stamped laminations or assembled core structures for electrical equipment are annealed to develop the desired core loss and permeability characteristics.

These grades are specifically developed for magnetic applications not requiring extremely low core losses or for those applications not requiring magnetic characteristics of high silicon electrical steel.
