Product Overview

0.23mm Cold Rolled Grain Oriented Silicon Steel (CRGO) is premium soft magnetic material manufactured for transformer core production. This group includes conventional grain oriented grades: 23Q090,23Q095,B23P085,B23P090 and HiB laser magnetic domain refinement grades B23R075,23QH080.

Through controlled rolling and high-temperature annealing, grains are aligned along rolling direction to deliver superior magnetic performance. Conventional 0.23mm CRGO offers stable magnetic property for standard distribution transformers, mutual inductors and reactor cores. HiB grades B23R075 and 23QH080 adopt laser domain refinement technology, featuring further decreased iron loss and lower running noise, ideal for high-efficiency main power transformers and high voltage equipment.

Mother coil width ranges from 700–1200mm, we provide longitudinal slitting service according to customers’ lamination drawings. All coils come with magnetic test reports and factory certification documents, complying with GB/T2521.2, IEC, JIS, EN and ASTM standards.

FAQs

What is the difference between 0.23mm conventional CRGO and HiB CRGO?

Conventional 23Q090,23Q095,B23P085,B23P090 have stable magnetic performance for standard distribution transformers. HiB grades B23R075 and 23QH080 adopt laser magnetic domain refinement, lower core loss and quieter operation, used for high-efficiency power transformers. HiB grades can upgrade replace conventional 0.23mm CRGO.

Can you slit 0.23mm CRGO coil to custom widths?

Yes. We provide longitudinal slitting service, cut mother coils to custom widths as per your transformer lamination drawings.

What documents can you provide for 0.23mm CRGO?

We supply mill test certificates, magnetic performance test reports and factory certification documents for export customs inspection and transformer factory quality check.

What is MOQ for 0.23mm CRGO silicon steel coil?

Minimum order quantity is 5 tons. Mixed grades within 0.23mm series are acceptable upon negotiation.

What is the surface coating on 0.23mm CRGO?

Uniform inorganic insulating coating. It provides good insulation between laminations, heat resistance and anti-sticking property during transformer core annealing.
