Big river steel has taken our cold rolled manufacturing capabilities even farther by providing crml steels.
Cold rolled lamination steel.
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.
1 1 this specification covers cold rolled carbon sheet steel used for magnetic applications.
Also called cold rolled lamination steel this material is the lowest cost material for volume applications.
Crml is an electrical grade of steel containing low amounts of alloy.
Cold rolled motor lamination crml astm a726.
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.
The steels used for these applications are designed to.
Electrical steel is usually manufactured in cold rolled strips less than 2 mm thick.
Ease of stamping and low tool wear help to contribute to the low cost of finished laminations.
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.
Carbon steel should be considered for applications where.
Lamination crml will remain a priority far into the future.
1 integrated mills lacking the specialized continuous annealing lines required for noes were provided.
These include electric motors generators and transformers.
Motor lamination steel is a specific cold rolled product tailored to create electromagnetic core materials for electrical equipment and components.
We also offer thin gauge low loss grades for special applications with technical support to better understand customer needs and recommend most cost effective.
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.
Our crml meets astm a726 standards for use in the electromagnetic core of fractional motors and other electrical equipment and components.
Electrical steel lamination steel silicon electrical steel silicon steel relay steel transformer steel is an iron alloy tailored to produce specific magnetic properties.
