Method of forming a hot stamped coated steel product

A hot stamped coated steel product, the hot stamped coated steel product comprising:

• a base steel;
• and
• a coating having a thickness of including, proceeding from the base steel outwards:
• (a) an interdiffusion layer,
• (b) an intermediate layer,
• (c) an intermetallic layer, and
• (d) a superficial layer,
• the base steel having a composition comprising:
• 0.15%<carbon<0.5%;
• 0.5%<manganese<3%;
• 0.1%<silicon<0.5%;
• 0.01%<chromium<1%;
• 0%<titanium<0.2%;
• aluminum<0.1%;
• phosphorus<0.1%;
• 0 ppm <=sulfur <=20 ppm;
• 0.0005%<boron<0.08%;
• nitrogen;
• a weight ratio of titanium content with respect to the nitrogen content being in excess of 3.42;
• a remainder being iron and impurities inherent in processing.
