The difference between standard and ASTMB196M-03's. --- Shape only round bars, ASTM standards specified in this standard form for the bars and strip cross-section has a circular, hexagonal Shaped and octagonal bars and rectangle strip; --- This standard is based on ASTMB196M-03 on the increase QBe2, QBe1.9, QBe1.9-0.1 and QBe1.7 grades; increase Plus heat processed and semi-hard state; for straightness modified, less than 1500mm length for straightness requirements when inferior to ASTM B196M-03 standards strictly; Mechanical tests before --- the mechanical properties of different test requirements, specified in this standard aging heat treatment each state a tensile test, hardness Test only when the user requires parties to carry out the mechanical properties after aging heat treatment test for hardness test, tensile test for the special user Do not be carried out when the requesting Party; ASTMB196M-03 standard specifies the nominal diameter or a parallel plane spaced not more than 10mm Bars (round, hexagonal, octagonal) and bar (square) and the cross-sectional area of not more than 100mm2 other sections were Tensile test, hardness test remaining. This standard is part of the material provisions of the elongation ratio ASTMB196M-03 standard is slightly Low, the other mechanical properties very demanding; --- The standard increases the product's internal quality requirements and test methods. The difference between the standard and ASTMB441-04. --- Shape only round bars, ASTMB441-04 standard form specified in this standard for the bar and the strip, a round cross-section Shaped, hexagonal and octagonal bars and rectangle strip; --- This standard adds QBe0.3-1.5 grades and thermal processing state; for straightness modified, when the length is less than 1500mm Straightness requirements better than ASTMB441-04 strict standards; --- Mechanical properties of different test requirements, this standard specifies the mechanical test before aging heat treatment each state a tensile test, hardness test Only when the user experience to carry out the requested Party, the mechanical properties after aging heat treatment test for hardness test, tensile test for the particular user When the requesting Party to carry out; ASTMB441-04 standard specifies the nominal diameter or parallel to the plane of spaced not more than 9.52mm Products and cross-sectional area of not more than 91mm2 other product shapes tensile test, a hardness test to rest; --- The standard increases the product's internal quality requirements and test methods. Instead of the standard YS/T 334-1995 "beryllium copper rod." Compared with this standard YS/T 334-1995, the main changes are as follows. --- This standard adds US C17000, C17200 and C17300 grade; product diameter tolerance, straightness, roundness and not Cut length has been adjusted; --- On the part of the tensile strength and elongation of the lower limit of the range has been adjusted; removed Brinell hardness, some additions and modifications Rockwell Hardness range; an increase of non-proportional extension strength requirements; --- For QBe0.6-2.5, QBe0.4-1.8, QBe0.3-1.5 grade products to increase the conductivity requirements; --- Increasing the product selected for a predetermined ultrasonic flaw detection test.
