Frequently Asked Questions:
-
What distinguishes DT4C from other pure iron grades?
DT4C offers enhanced magnetic properties with lower carbon content compared to standard pure iron, making it suitable for precision electromagnetic applications where minimal core loss is critical. -
Can I request specific tolerance classes under GB/T 14981?
Yes, we provide multiple tolerance classes (A, B, C) upon request to match your machining precision requirements. -
What packaging options are available?
Standard bundles with steel strapping or customized packaging solutions to prevent transit damage and facilitate handling. -
How does hot-rolling affect magnetic performance?
Hot-rolling optimizes grain structure uniformity, resulting in improved magnetic permeability and reduced hysteresis losses. -
Is surface rust prevention provided?
A natural oxide film forms during processing which provides temporary protection; optional anti-rust treatments are available upon request. -
What is the lead time for customized diameters?
Standard diameters ship in 7-10 days; non-standard sizes require 15-20 days for production with prior consultation. -
Do you provide material certification?
Each batch includes a test certificate detailing chemical composition and mechanical properties per GB/T 14981.
