ASTM A234 WP91 pipe fittings cap
ASTM A234 WP91 is low content alloy steel,so its hardness is higher than carbon steel,so its have better performance for the abrasive resistance and corrosion resistence.So the ASTM A234 WP91 pipe fitting is more widely used for the machine parts compared with carbon steel.
