Nuclear Transport Flask
This is a series of steels with increasing levels of boron 0.20/0.29% to 1.75/2.25%. It is used entirely in the nuclear industry for neutron absorption.
Approximate Composition - 18% Cr, 12% Ni, 0.20/0.29% to 1.75/2.25% B (Grades found only in ASTM standard A887).
This grade combines the following characteristics:
- Excellent levels of neutron absorption preventing criticality of nuclear reactions
- Moderate corrosion resistance lower than grade 304 but acceptable in typical nuclear environments
- Reduced impact toughness due to formation of borides
- Formable with care – increased bending radius compared to 304
- Weldable with care – boron containing consumables
- Increased levels of tool wear in machining
- Higher levels of boron facilitated by powder metallurgy due to loss of hot ductility in conventional melting plus hot rolling
