China Polar Research Center and the China Classification Society (CCS), together
with several domestic steelmakers, after more than two years of R&D resolved a
series of technical problems for high-strength steel for polar vessels and have
produced a domestic polar-ship high-strength steel. Relevant steelmakers have
begun certification work; Baoshan Iron & Steel Co., Ltd.'s polar-ship
high-strength steel is the first product to receive CCS certification.
