摘要： Steel is obtained which comprises by wt %, C: 0.001-0.025%, Si: not more than 0.60%, Mn: 0.10-3.00%, P: 0.005-0.030%, S: not more than 0.01%, Al: not more than 0.10%, Cu: 0.1-1.5%, Ni: 0.1-6.0%, B: 0.0001-0.0050%, and the balance being Fe and inevitable impurities; since the steel contains C and P in small contents, stable amorphous rusts are formed on the surface thereof at an early stage; and steel simultaneously realizes excellent weather resistance, material weldability and toughness particularly in an environment such as a seashore district and the like where salt is present in a large amount.

摘要： The invention provides a steel product having superior weathering which is coated with a rust layer containing 50 or more weight % of non-crystalline rust, a method of producing the steel product, and a method of forming weathering protective rust on a material surface of the steel product. A material of a steel product is placed in an atmosphere in which the dew point is kept constant and the temperature of the steel product material is repeatedly varied between a temperature range of 5.degree. C. or more higher than the dew point and a temperature range of 5.degree. C. or more lower than the dew point. Weathering protective rust is thereby formed on the material surface of the steel product and a steel product having superior weathering is obtained. Preferably, the atmosphere contains 15 to 50 volume % of oxygen gas, and the temperature of the steel product is varied at a rising rate of 0.1 to 2.degree. C./minute and a lowering rate of 0.01 to 2.degree. C./minute. Alternatively, a desired steel product can also be obtained by placing a material of the steel product in an atmosphere containing 15 to 50 volume % of oxygen gas, keeping constant the dew point in the atmosphere, and keeping the temperature of the steel product material in the atmosphere at a certain value in a temperature range between a temperature 5.degree. C. lower than the dew point and a temperature 20.degree. C. lower than the dew point; or by placing a material of the steel product in an atmosphere containing 15 to 50 volume % of oxygen gas, and forming and keeping a water film with a thickness not more than 500 .mu.m but not less than 50 .mu.m on a material surface of the steel product.
摘要翻译：本发明提供一种具有优良耐候性的钢制品，其涂有含有50重量％以上非结晶锈的锈层，该钢制品的制造方法以及在该材料表面上形成耐候性锈蚀的方法钢制品。将钢材的材料放置在露点保持恒定的气氛中，并且钢产品材料的温度在5℃以上的温度范围内反复变化，并且温度范围比露点低5℃或更高。由此，在钢材的材料表面形成耐候性保护锈，得到耐候性优异的钢制品。优选气氛含有15〜50体积％的氧气，钢产品的温度以0.1〜2℃/分钟的升高速度变化，0.01〜2℃/分钟的降低速度。或者，也可以通过将钢材的材料放置在含有15〜50体积％的氧气的气氛中，使大气中的露点保持恒定，并将钢材的温度保持在在一定温度范围内的气氛在比露点低5℃的温度和比露点低20℃的温度范围内; 或通过将钢制品的材料放置在含有15〜50体积％的氧气的气氛中，在其材料表面上形成并保持厚度不大于500μm〜50μm的水膜钢铁产品。
