GOST 6235-91. Sheets and strip, of Nickel. Specifications.
Sheets and strips of Nickel are manufactured in compliance with GOST 6235−91 for the production schedules of the grades NP1, NP2, refinery, NP4 soft (annealed), semi-hard and hard (unannealed) condition. Soft Nickel strip thickness of 0.15 mm and a width exceeding 60 mm are made with oblasnoy bilateral cleaning the surface with wire brushes.
The rolled surface shall be clean, free from contaminants and smooth, without captivity, cracks, bubbles, delaminations, scale, holes, dents, scratches and sunsets. On the surface allowed the local risks, dents, fingerprints from the rolls, not outputting the sheets in the control sweep for half of limit deviations for thickness. Traces of unburned lubricant, the color of a tint and a local discoloration on the surface of the strips, intended for the manufacture of parts of electric vacuum and semiconductor devices are not permitted. Stripped surface allowed local bright spots and stripes.
|Sheet thickness (mm)||The maximum deviation of the thickness when the width of sheet (mm)|
|500||600 and 700||800|
According to GOST 6235−91 the length of the sheets should be 500 — 2000 mm tolerance on length of sheets dimensional and multiple lengths shall not exceed minus 20 mm. Thick hot-rolled strip and limit deviation (in millimetres) shall be as given below.
|Thickness||The tolerances on the thickness||Thickness||The tolerances on the thickness|
|5,0||Mobility in soil -0,35||13,0||-0,80|
|6,0||Mobility in soil -0,35||14,0||-0,80|
According to GOST 6235−91 width hot rolled strips and limit deviations must meet the following.
|Width (mm)||Maximum deviations in width with the thickness (mm)|
|5,0||6 — 10,0||11 — 20|
|100, 150, 300||-4||-10||-|
Length of hot-rolled strips should be 400 — 2000 mm.
