Features of heat treatment Casting parts chemical engineering at STP 26.260.484 2004 and castings on the other 26-06-1414-84 should be subjected to quenching in water from 1100-1150 °C, to withstand during heating for hardening 1.5 h. In the case when under the influence of aggressive environments have revealed a tendency of steel to stress corrosion cracking, apply stabilizing step annealing regime: heating up to 1100-1150 °C, exposure to 1.5 h, cooling with the furnace to 950 °C, exposure 2 h, cooling with the furnace to 300 °C, then - on the air. If steel produced by replacing titanium with niobium, the heat treatment is stored. On the other 26-06-1414-84 castings supplied in the heat treated condition. In agreement with the customer, the castings can be supplied without heat treatment. In this case, the heat treatment produces the customer.
Defect welding Defects of castings on the other 26-06-1414-84 affecting their strength and integrity and detract from the appearance of products are subject to correction. Their types, sizes and quantity are specified in the order. To identify and repair of hidden defects of castings subjected to the test of density, must be provided for prior machining and subsequent testing for density. Defects of castings produced in electric arc or argon-arc welding according to the technology supplier. After correcting the defects, welding castings should be heat treated at the specified mode. No need to make heat treatment after welding sections of the casting, spaced at a minimum distance of 30 mm from the aggressive environment. The need and methods of control of the casting after welding defects specified in the order.
Casting Casting on the other 26-06-1414-84 configuration, size and weight shall conform to the drawings and to the requirements of GOST 2009. Forming the slope are assigned according to GOST 3212 supplier. Surface of castings shall be cleaned in accordance with the requirements of GOST 2176. It is allowed to leave the bays, burrs, remnants of sprues and metal penetration in areas inaccessible to elektroniski, chisel, grinding on the surfaces subjected to further mechanical processing. Segment profits Letnikov and larger bays may be performed by machining, anodic-mehanicheskoj sharp, and flame or arc cutting. In the case of a flame or electric arc risky the size and shape of remnants cut of profits and sprues ostanavlivajutsja casting supplier and entered in the casting drawing, which is coordinated with the customer. Flame cutting must be performed before the heat treatment. Minor defects do not reduce the strength and not impairing the appearance of products are allowed on castings without patches. The types, sizes and number of defects permitted without the hotfix specified in the order.
