1. the corrosion process for show of a 300M crystalline grain of steel degree, it is characterised in that comprise the following steps:

  • (1) 300M crystalline grain of steel degree sample is carried out pretreatment;

    (2) caustic of 300M crystalline grain of steel degree sample is configured;

    (3) caustic that heater configuration is good is to 30 ~ 40 DEG C, and keeps temperature constant;

    (4) the 300M crystalline grain of steel degree sample handled well is put in the caustic of temperature constant;

    (5) in corrosion process, the erosional surface of continuous wiping 300M crystalline grain of steel degree sample, after wiping 10 ~ 20 minutes, takes out 300M steelGrain size sample;

    (6) with the cold water wash 300M crystalline grain of steel degree sample of flowing, while cleaning, the corrosion trace of sample erosional surface is cleanedMark;

    (7), after having cleaned, the erosional surface at 300M crystalline grain of steel degree sample instills ethanol, then dries up sample;

    (8) finally observe the pattern of 300M crystalline grain of steel degree sample and evaluate the grain size number of sample.
