Ship supplies of gloves: gloves: that labor protection gloves gloves gloves are well known in one of the oldest marine fire doors, the first layer of leather, goat, pig and sheep skins, leather gloves are made of these into, and difficult to be damaged, a longer service life and fine processing such comfortable wearing leather gloves, accurate grasp objects, in addition to the leather glove also has good heat insulating properties and advantages. [Jada Industry and Trade to recommend star product - ship supplies] general strength hull structural steel is divided into A, B, C, D4 levels, this four levels of yield strength steel (not less than 235N/mm ^ 2) and tensile strength (400 ~ 520N/mm ^ 2) the same, but the impact energy at different temperatures just not the same; high-strength hull structural steel minimum yield strength divided their intensity level in Tianjin Marine fire doors, each intensity level and according to the different impact toughness into A, D, E, F4 level. A32, D32, E32, F32 yield strength of not less than 315N/mm ^ 2, the tensile strength of 440 ~ 570N/mm ^ 2, A, D, E, F, respectively, each of which may respectively 0 °, -20 °, -40 °, -60 ° in the case of impact toughness can be achieved; A36, D36, E36, F36 yield strength of not less than 355N/mm ^ 2, the tensile strength of 490 ~ 620N/mm ^ 2 wholesale marine fire doors, A, D, E, F, respectively, each of which may in each case 0 °, -20 °, -40 °, -60 ° the impact toughness can be achieved; A40, D40, E40, F40 yield strength of not less than 390N/mm ^ 2, the tensile strength of 510 ~ 660N/mm ^ 2, A, D, E, F, respectively, each of which may in each case 0 °, -20 °, -40 °, -60 ° the best reaching impact toughness.
