Frequently Asked Questions
What is the advantage of Q460FTC over Q420FTC?
Q460FTC offers higher yield strength (460 MPa vs. 420 MPa) while maintaining the same 0°C impact toughness (47J). This allows for lighter designs and even larger wind turbines.
Is Q460FTC suitable for offshore wind?
Yes, its 0°C impact meets requirements for most temperate and cold offshore zones. For arctic offshore, consider Q460FTE or Q460FTF with lower temperature grades.
What is the MOQ for Q460FTC plates?
25MT for plates, 50MT for coils. Trial orders (10-15MT) may be accepted after discussion.
Third-party inspection available?
SGS, BV, TÜV inspection can be arranged at extra cost; mill certificate EN 10204 3.1 is always included.
