成本更低的耐腐蚀性是Krupp Stahl AG公司研制的Nirosta 4003钢的主要优点。Nirosta 4003钢的耐腐蚀性好于非合金或低合金钢,但其成本却低于高合金不锈钢,它为设计工程师提供了较高的静态和动态强度,其屈服强度为320N/mm~2。它焊接容易,制作简便,而且既耐热又耐磨。在作了广泛深入的试验之后,德国联邦铁路已批准将Nirosta 4003钢用于制造客车和货车,Krupp Maschinentechnic公司已将之用于ICE动车的侧板和后板。它早已
The lower cost of corrosion resistance is the main advantage of Nirosta 4003 steel developed by Krupp Stahl AG. Nirosta 4003 is more corrosion resistant than non-alloy or low-alloy steels, but at a lower cost than high-alloy stainless steels. It offers design engineers a high static and dynamic strength with a yield strength of 320 N / mm 2. It is easy to weld, easy to make, and resistant to heat and wear. After extensive and extensive testing, the German Federal Railroad has approved the use of Nirosta 4003 steel for the manufacture of passenger cars and trucks, which Krupp Maschinentechnic has used for the side and back panels of ICE motor cars. It’s already
